walkopts for kwexpand, kwshrink, kwfiles commands
kwfiles optionally shows ignored files or all flagged
Use pathto method to print kw filenames if possible.
Commands abort with meaningful error
_weedcandidates renamed to _weedfiles, and only for commands.
For kwrepo.commit we could get modified + added from
kwrepo.status(match=ui.kwfmatcher) -- but this would mean
to read manifest before commit, and again after for expansion.
