Description

Mercurial's locate command will exit with status 1 when no files are
found. We use hg locate -r <REV> set:size(0) to locate empty files.
However, when there are no empty files, we will get None instead of
empty output because of Mercurial's status code. We now only try to
parse the list of files when there is output to avoid this issue.

Testing Done

Ran unit tests.
