Instead of reverting to 0.0.0, keep the same version number (eg. 1.2.4)
but add an extra suffix with the change count,
eg. 1.2.4-6-tb35d95ad7-gcb8be72e6. This avoids the problem where a
small patch causes the code to report a totally different version to
the server, which might change its behaviour based on version code.
(The server might enable various bug workarounds since it thinks
0.0.0 is very old.)

This option isn't available on slightly older versions of git. We were
no longer using the real describe functionality anyway, so let's just do
something simpler to detect a dirty worktree.
While we're here, fix up a little bit of sh style.

The output of `wc -l` on darwin starts with a tab:
git rev-list 266f6548611ad0de93e7470eb13731db819f184b..HEAD | wc -l

git worktrees have a .git file rather than a .git directory, so building
in a worktree caused version.sh to generate an error.
