Fix theoretical issue in filecommit.
If the file was copied, we don't want to reuse the original entry.
I think this is mostly a theoretical issue - when there are copies,
fp1 == nullid, so it's very unlikely that the fl.cmp(fp1, t) would
think the file was unmodified. In any case, if there was a copy,
we should forcefully create a new entry.
