gitweb.perl suggestion

Currently, if I go to

  http://server/gitweb/project/<commit-sha1>

I get to the shortlog page, which is not as useful as the commit page. But changing this to have a default `commit' action isn't right either since the shortlog is more appropriate with

  http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

So how about changing this:

  $input_params{'action'} ||= "shortlog";

to this:

  $input_params{'action'} ||= ((defined $parentrefname) ? "shortlog" : "commit");

which will make the first case show the commit, and the second show the shortlog?
