git-annex/Command/Version.hs
Joey Hess 944c51ba26 improve version checking for v3
Do not set annex.version whenever any command is run. Just do it in init.
This ensures that, if a repo has annex.version=3, it has a git-annex
branch, so we don't have to run a command every time to check for the
branch.

Remove the old ad-hoc logic for v0 and v1, to simplify version checking.
