Hi bug-gnu-emacs,

vc-git-region-history currently stops at the first rename, instead of continuing across renames.  This is because it doesn't pass --follow to git.  The original author put the required option "--follow" in a comment, adding "FIXME: not supported?".

Indeed, `git log -p --follow -L5,25:file.c' doesn't work.  But `git log -p --follow -L5,25:file.c file.c' does work (note the extra mention of the file name).

Any arguments against the attached patch?

(CCing Stefan, since you're the last one who modified this function)

Clément.
