[RFC PATCH 0/1] for-each-ref: Add '--no-symbolic' option

[Eric Freese <ericdfreese@gmail.com>]

Hi,

I was recently using git-for-each-ref in a script to get a list of
remote refs that pointed at a particular commit so that they could
automatically be updated and pushed back to that remote. This fails when
it comes across refs/remotes/origin/HEAD, which is a symbolic link.

I was able to solve the problem with:

```
git for-each-ref ... --format="%(refname) %(symref)" | grep " $"
```

But that feels a little clumsy to me. I would have expected there to be
a flag like `--no-symbolic` that would exclude symbolic refs from the
output. So I went ahead and added it :)

I could forsee this option also being added to git-branch and git-tag,
but decided to keep it to git-for-each-ref to test the waters before
investing any further time into it.

Cheers
