var: Don't require to be in a git repository.

flichtenheld · gitster · commit 2fba8366ed1e · 2008-03-15T01:43:56.000-07:00
git var works fine even when not called in a git repository. So
don't require it.

This will make it possible to remove this pre-condition for some
other git commands as well.
