[PATCH 1/2] chdir after computing new cwd in check_repository_format_gently

In preparation for adding a check before the chdir.
This should be a no-op because the cwd is not read in the interim
and any nonlocal exits either chdir to an absolute path or die.

I sent this in a few weeks ago, but got no response.  Probably because I
messed up the formatting.  Hopefully I'm getting it right this time.
