Subject: 24.4.50; grep-files-aliases should use major mode instead
Date: Wed, 01 Oct 2014 08:52:30 +0100

I was visiting a ".h" file that had a major mode cookie to set the major
mode to C++.  Then I tried vc-git-grep.  It offered to default to
searching "*.[ch]" files.

This seems a bit sub-optimal to me, as Emacs already knows that the file
is C++, not C.  Defaulting to the "C++"-ish set of files would be more
useful.

Maybe grep-files-aliases could be based on major mode and not file
extension; or maybe at least the major mode could be tried first.
