Just a minor suggestion meta suggestion: post your patches by attaching
the output from 'git format-patch', rather than inlining the output of
git diff.  That will avoid patch corruption due to line-wrapping, like
in the above quote (although that line is also a bit long, and you
should break it manually).

> Changelog entry:
> * lisp/progmodes/grep.el (grep-read-files): Allow major modes to
> define file name to use for default search pattern
> * lisp/dired.el (dired-grep-file-name-for-default-pattern): Use file
> at point
> for grep file name pattern

And the ChangeLog entry then goes in the git commit message.  It's much
easier for other people to apply your patch that way.
