git and the loss of revision numbers

It is good to have a revision number available through uname -a or otherwise.

Not sure about how Haiku does that, but Haiku uses tags that are noticeable when downloading (git clone or pull).  I believe tags show the revision number.

I haven't run Haiku in several years; all I have is USB-stick image from November 2012, downloaded 2014 (?), too old to be able to compile newer versions, and trying to cross-compile from FreeBSD or NetBSD has never been successful.
