logcmdutil: also check for copies in null revision and working copy

It's safe (and fast) to look for copies in the null revision, and it's
incorrect not to look for them in the working copy, so let's look in
both places.

Differential Revision: https://phab.mercurial-scm.org/D6544

#!/usr/bin/env python
#
# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
