Re: [PATCH/RFC] Clarified how pattern works in documentation to git-show-ref.

Garry Dolley [off-list ref] writes:

Several people in #git, including myself, thought that the following would
show all refs:

  git show-ref '*'

Since that is not how the pattern patching works, clarification was needed
in the documentation.

I think including a little more info in the docs regarding the pattern would
be helpful.  Comments?

Would be helpful.

It may be worthwhile to know that that "pathspec" limiting done by
revision traversal ("git log", "git rev-list") and diff is also without
globbing, but it is a head-match, and match is forced at '/' boundary.

ls-files and grep know how to glob, on the other hand.
