Overriding an @additional_branch_refs configuration variable with

refs/heads and refs/wip (refs/heads is hardcoded). Might be useful for
gerrit setups where user branches are not stored under refs/heads/.


The description of this change starts with technical details,
instead of starting with intent of this change.

Perhaps (this is only a proposal)

  Introduce @additional_branch_refs configuration variable, holding
  names of references to be considered branches; by default empty.
  For example setting it to ('wip') will make gitweb ...


BTW. I have thought at first that is something similar to 'remote_heads'
feature, which among others adds 'remotes' section to 'summary' view
displaying refs/remotes/* refs... but no, gitweb still doesn't treat refs/remotes as branches, even with this feature set.

Nb. why new configuration variable, and not new %feature?

git-for-each-ref accepts more than one pattern. Why not simply

   	open($fd, "-|", git_cmd(), 'for-each-ref',
   	     '--format=%(committer)',
   	     '--sort=-committerdate',
   	     '--count=1',
  -	     'refs/heads') or return;
  +	     get_branch_refs()) or return;

Then we won't need List::Util::min.
