This string is passed to the scan program via the -format
argument.  This format is identical to the default except that
additional hints for fontification have been added to the fifth
column (remember that in Emacs, the first column is 0).

The values of the fifth column, in priority order, are: "-" if
the message has been replied to, t if an address on the To: line
matches one of the mailboxes of the current user, "c" if the Cc:
line matches, "b" if the Bcc: line matches, and "n" if a
non-empty Newsgroups: header is present.

#@390 This regular expression matches the message body fragment.

Note that the default setting of `mh-folder-font-lock-keywords'
expects this expression to contain at least one parenthesized
expression which matches the body text as in the default of
"\\(<<\\([^\n]+\\)?\\)".  If this regular expression is
not correct, the body fragment will not be highlighted with the
face `mh-folder-body'.
(defvar mh-scan-body-regexp "\\(<<\\([^\n]+\\)?\\)" (#$ . 2497))
#@658 This regular expression matches the current message.

It must match from the beginning of the line.  Note that the
default setting of `mh-folder-font-lock-keywords' expects this
expression to contain at least one parenthesized expression which
matches the message number as in the default of

  "^\\( *[0-9]+\\+\\).*".

This expression includes the leading space and current message
marker "+" within the parenthesis since it looks better to
highlight these items as well.  The highlighting is done with the
face `mh-folder-cur-msg-number'.  This regular expression should
be correct as it is needed by non-fontification functions.  See
also `mh-note-cur'.
(defvar mh-scan-cur-msg-number-regexp "^\\( *[0-9]+\\+\\).*" (#$ . 2958))
#@437 This regular expression matches a valid date.

It must not be anchored to the beginning or the end of the line.
Note that the default setting of `mh-folder-font-lock-keywords'
expects this expression to contain only one parenthesized
expression which matches the date field as in the default of
"\\([0-9][0-9]/[0-9][0-9]\\)"}.  If this regular expression
is not correct, the date will not be highlighted with the face
`mh-folder-date'.
(defvar mh-scan-date-regexp "\\([0-9][0-9]/[0-9][0-9]\\)" (#$ . 3696))
#@608 This regular expression matches deleted messages.

It must match from the beginning of the line.  Note that the
default setting of `mh-folder-font-lock-keywords' expects this
expression to contain at least one parenthesized expression which
matches the message number as in the default of

  "^\\( *[0-9]+\\)D".

This expression includes the leading space within the parenthesis
since it looks better to highlight it as well.  The highlighting
is done with the face `mh-folder-deleted'.  This regular
expression should be correct as it is needed by non-fontification
functions.  See also `mh-note-deleted'.
(defvar mh-scan-deleted-msg-regexp "^\\( *[0-9]+\\)D" (#$ . 4210))
#@588 This regular expression matches "good" messages.

It must match from the beginning of the line.  Note that the
default setting of `mh-folder-font-lock-keywords' expects this
expression to contain at least one parenthesized expression which
matches the message number as in the default of

  "^\\( *[0-9]+\\)[^D^0-9]".

This expression includes the leading space within the parenthesis
since it looks better to highlight it as well.  The highlighting
is done with the face `mh-folder-msg-number'.  This regular
expression should be correct as it is needed by non-fontification
functions.
(defvar mh-scan-good-msg-regexp "^\\( *[0-9]+\\)[^D^0-9]" (#$ . 4891))
#@284 This regular expression finds the message number width in a scan format.

Note that the message number must be placed in a parenthesized
expression as in the default of "%\\([0-9]*\\)(msg)".  This
variable is only consulted if `mh-scan-format-file' is set to
"Use MH-E scan Format".
(defvar mh-scan-msg-format-regexp "%\\([0-9]*\\)(msg)" (#$ . 5556))
#@211 This is a format string for width of the message number in a scan format.

Use "0%d" for zero-filled message numbers.  This variable is only
consulted if `mh-scan-format-file' is set to "Use MH-E scan
Format".
(defvar mh-scan-msg-format-string "%d" (#$ . 5914))
#@216 This regular expression extracts the message number.

It must match from the beginning of the line.  Note that the
message number must be placed in a parenthesized expression as in
the default of "^ *\\([0-9]+\\)".
(defvar mh-scan-msg-number-regexp "^ *\\([0-9]+\\)" (#$ . 6183))
#@61 This regular expression matches overflowed message numbers.
(defvar mh-scan-msg-overflow-regexp "^[?0-9][0-9]" (#$ . 6469))
#@199 This regular expression matches a particular message.

It is a format string; use "%d" to represent the location of the
message number within the expression as in the default of
"^[^0-9]*%d[^0-9]".
(defvar mh-scan-msg-search-regexp "^[^0-9]*%d[^0-9]" (#$ . 6600))
#@586 This regular expression specifies the recipient in messages you sent.

Note that the default setting of `mh-folder-font-lock-keywords'
expects this expression to contain two parenthesized expressions.
The first is expected to match the "To:" that the default scan
format file generates.  The second is expected to match the
recipient's name as in the default of
"\\(To:\\)\\(..............\\)".  If this regular
expression is not correct, the "To:" string will not be
highlighted with the face `mh-folder-to' and the recipient will
not be highlighted with the face `mh-folder-address'
(defvar mh-scan-rcpt-regexp "\\(To:\\)\\(..............\\)" (#$ . 6871))
#@610 This regular expression matches refiled messages.

It must match from the beginning of the line.  Note that the
default setting of `mh-folder-font-lock-keywords' expects this
expression to contain at least one parenthesized expression which
matches the message number as in the default of

  "^\\( *[0-9]+\\)\\^".

This expression includes the leading space within the parenthesis
since it looks better to highlight it as well.  The highlighting
is done with the face `mh-folder-refiled'.  This regular
expression should be correct as it is needed by non-fontification
functions.  See also `mh-note-refiled'.
(defvar mh-scan-refiled-msg-regexp "^\\( *[0-9]+\\)\\^" (#$ . 7536))
#@605 This regular expression matches messages sent to us.

Note that the default setting of `mh-folder-font-lock-keywords'
expects this expression to contain at least two parenthesized
expressions.  The first should match the fontification hint (see
`mh-scan-format-nmh') and the second should match the user name
as in the default of

  ^ *[0-9]+.\\([bct]\\).....[ ]*\\(..................\\)

If this regular expression is not correct, the notation hints
will not be highlighted with the face
`mh-mh-folder-sent-to-me-hint' and the sender will not be
highlighted with the face `mh-folder-sent-to-me-sender'.
(defvar mh-scan-sent-to-me-sender-regexp "^ *[0-9]+.\\([bct]\\).....[ ]*\\(..................\\)" (#$ . 8221))
#@867 This regular expression matches the subject.

It must match from the beginning of the line.  Note that the
default setting of `mh-folder-font-lock-keywords' expects this
expression to contain at least three parenthesized expressions.
The first is expected to match the "Re:" string, if any, and is
highlighted with the face `mh-folder-followup'.  The second
matches an optional bracketed number after "Re:", such as in
"Re[2]:" (and is thus a sub-expression of the first expression)
and the third is expected to match the subject line itself which
is highlighted with the face `mh-folder-subject'.  For example,
the default (broken on multiple lines for readability) is

  ^ *[0-9]+........[ ]*...................
  \\([Rr][Ee]\\(\\\=[[0-9]+\\]\\)?:\\s-*\\)*
  \\([^<\n]*\\)

This regular expression should be correct as it is needed by
non-fontification functions.

produced by "inc".
