morestatus: don't crash with different drive letters for repo.root and CWD

Previously, if there were unresolved files and the CWD drive was different from
the repo drive, `hg status -v` would page the normal status, followed by the
exception header.  A stacktrace was waiting when the pager exited.  The
underlying cause was the same as f445b10dc7fb.

Unfortunately, I don't see any reasonable way to write a test this [1].
