gitweb: Improve behavior for actionless path_info gitweb URLs Eli Barzilay noticed that http://server/gitweb/project/<commit-sha1> link goes to 'shortlog' view, while 'commit' view would be more useful, but that 'shortlog' action is more apropriate for http://server/gitweb/project/<commit-sha1>..<other-commit-sha1> links. Therefore for the case when we don't have either action, or filename, or parent hash [base] in path_info-based URL, i.e. for http://server/gitweb/project/<object-id> link, instead of using 'shortlog' view we allow dispatch() subroutine to detect type of object and use appropriate action (in most case it would be either 'commit' action, or 'tag', or 'tree' for top directory).
