It appears to not _sort_ the output by committerdate, as it should with '--sort=-committerdate'.

1442:[gitweb/web!git]$ git for-each-ref --format="%(refname):%09%(committer)" \
  --sort=-committerdate refs/heads

1443:[gitweb/web!git]$ git --version git version 1.5.3.5

Note that git-for-each-ref with those options returns most recent head first, sorting output by date of commit (date of adding to repository)

Gitweb should not (and I think does not) have 'master' hardcoded anywhere. It might use HEAD in some cases you don't want it to...

Older version of gitweb used HEAD branch for'last changed' info on the projects list page. That is why I asked about gitweb version.

But this is not the case of your problem:
1. Your gitweb is new enough to use git-for-each-ref. It use
   git for-each-ref --format="%(committer)" --sort=-committerdate 
                    --count=1 refs/heads
2. Looking at 'heads' view (or 'heads' part of summary view) one can see
   that m29 is current branch (HEAD), and it is most recent.

Strange...
