Please don't use "git log" for something like this.

Sure, it works, but it's kind of silly to say "I want a log, except I want
only a single entry, and btw, I don't actually even want the log entry for
that single entry at all, just the hash".

It boils down to "I want a log, except with none of the log part". It
should make you go "Do I really want a log"?

If you really want the hash, maybe just using "git rev-parse HEAD" would
do it.

However, in this case I think _any_ of those would be wrong. Wouldn't it
make sense to use the same thing that we already compute for 'uname'
(scripts/setlocalversion)? Especially as that one already knows how to
handle other SCM's too (ie the whole hg/svn parts).

That script also ends up using a nicer format, ie it uses "git describe"
to give a better idea of where it all is.
