[PATCH] Do not ignore hidden refs

[Petr Baudis <pasky@suse.cz>]

Some of the ref manipulation tools (git-for-each-ref and git-show-ref in
particular) would not handle hidden (~ /^\./) refs. This may be an
acceptable or possibly even desirable behaviour for the ref walkers and
repackers, but git-show-ref hiddenrefname must work.

This makes Git not ignore hidden refs at all. I'm not opposed to making
some particular parts of the ref interface to continue to ignore hidden
refs, but the restriction cannot be so deep.
