I've noticed this little issue in our telemetry:

versions

The commit hashes appended to the version strings are of different lengths, even for exactly the same version.

As it turns out we use git rev-parse --short HEAD to grab those, and, to quote the git manpage (emphasis mine):

--short[=length]

Same as --verify but shortens the object name to a unique prefix with at least length characters. The minimum length is 4, the default is the effective value of the core.abbrev configuration variable (see git-config(1)).

So it just picks either whatever is the default (which can vary depending on the exact installed git version) or whatever was configured in ~/.gitconfig.

So this PR makes those hashes always at least 11 characters long. (Since that's currently the longest one in our telemetry.)
