copies: delete a redundant cleanup step in _chain()

The check is redundant since d5edb5d3a337 (copies: filter out copies
when target is not in destination manifest, 2019-02-14). To test that
hypothesis, I made this change in the commit that commit, but all
tests still passed. I think the case was necessary before then, we
just didn't have tests for it.

Differential Revision: https://phab.mercurial-scm.org/D6275

Address commentary in manifest.excludedmanifestrevlog.add -
specifically we should improve the collaboration with core so that
add() never gets called on an excluded directory and we can improve
the stand-in to raise a ProgrammingError.

Reason more completely about rename-filtering logic in
narrowfilelog. There could be some surprises lurking there.

Formally document the narrowspec format. For bonus points, unify with the
server-specified narrowspec format.

narrowrepo.setnarrowpats() or narrowspec.save() need to make sure
they're holding the wlock.

The follinwg places do an unrestricted dirstate walk (including files outside the
narrowspec). Some of them should perhaps not do that.

 * debugfileset
 * perfwalk
 * sparse (but restricted to sparse config)
 * largefiles
