At least with tags, the user can assume NAME-gREV means commit whose abbrev is REV that is descendant of NAME. HEAD is not necessarily so.
Having said that, in order to avoid barfing, we have to have something there, and HEAD is already special in many aspects anyway (e.g. by only saying HEAD you cannot tell which branch's tip you are talking about), it might be good enough.
I am just wondering if there is some other obvious substitute that is better than HEAD. "GIT-g%s" is not it ("g" already stands for GIT).
Another possibility is just to do
puts(sha1_to_hex(cmit->object.sha1))
in this case. I tend to like that better somehow; it makes things more explicit.
