commit 5e54fb308c7ad735d944068c063de6ac5276b93a
from: Stefan Sperling <stsp@stsp.name>
date: Fri May 31 13:01:03 2019 UTC

test and fix 'got revert' with a path in a sub-directory

Relax input path requirements of got_object_id_by_path() to
make things easier to callers. Allows the revert code to pass
a path from the file index in lieu of a repository path.
