Ediff regression

[Chong Yidong]

Something in the following checkin broke patch highlighting:

2007-06-12  Michael Kifer  <address@hidden>
        
        * ediff-mult.el
        (ediff-meta-buffer-brief-message,ediff-meta-buffer-verbose-message):
        new variables.
        (ediff-meta-buffer-message): variable deleted.
        (ediff-verbose-help-enabled): new variable.
        (ediff-toggle-verbose-help-meta-buffer): new function.
        (ediff-redraw-directory-group-buffer): made aware of short/verbose
        message options
        
        * ediff-ptch.el (ediff-context-diff-label-regexp): better regexp.
        (ediff-fixup-patch-map): improved heuristic.

To see this, save the following diff to a file foo.patch and open it.
The body of the patch will be highlighted as though it were a header.
The problem did not exist before the checkin.

diff -c configure.in.\~1.452.\~ /home/cyd/emacs/configure.in
