Re: git grep doesn't follow symbolic link

When using git grep, symbolic links are not followed.
Is it a wanted behavior ?

I'd imagine so: symbolic links are not portable across different file
systems; Git's internal representation of a symbolic link is a file
containing the path of the file to be linked to.

I'd actually welcome a fix to this general area, for an entirely
different reason.  With bash and ordinary diff I can do things like

  diff -u <(ls) <(cd elsewhere && ls) | less

But I lose all the cute features of git-diff.  I *could* say

  git diff --no-index <(ls) <(cd elsewhere && ls)

and it helpfully tells me

  diff --git 1/dev/fd/63 2/dev/fd/62
  index 55ccbe5..d796c45 120000
  --- 1/dev/fd/63
  +++ 2/dev/fd/62
  @@ -1 +1 @@
  -pipe:[607341]
  \ No newline at end of file
  +pipe:[607343]
  \ No newline at end of file

Of course that's diff and not grep, but I think they suffer from the
same flaw: they share the file-kind handling logic of the rest of git in
a case where it's not very helpful.
