Subject: [PATCH] first support for inotify
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Just automatically update gitk when working in a terminal on the same repo
Open points for now:
- release watches for deleted directories seems to
cause problems in tcl-inotify (so I don't)
I'm not sure how often that happens in ".git/"
- I only call "updatecommits" and I don't know if there is a usecase
where I should be calling "reloadcommits"
