Revert to using status for kw-commands cmdutil.bail_if_changed has to call status stat'ing working dir. This renders the whole walk experiment mute, duh. On the upside kwexpand/kwshrink can be applied to selected clean files, while there are local changes in other files. bail_if_changed compatibility wrapper not needed anymore.

Test if warning about non-existing files is triggered

cwd optional argument of _pathto to simplify _kwfwrite

Use pathto to display nonexisting files

kwexpand/kwshrink: warn about nonexisting files

_overwrite method for kwrepo.commit, kwexpand, kwshrink File selection (kwexpand/kwshrink) in _kwfwrite method.

Sort files before overwriting

_iskwfile checking method for kwrepo.commit, kwexpand/kwshrink

Walk manifest in kwexpand/kwshrink

For overwriting commands use node and manifest to speed up walk

kwfiles: change option "ignored" to "ignore", add option "untracked" "ignore" like corresponding config value. "untracked" allows quick check if a new file that has not been added yet would be target for expansion. Update help accordingly.

File collections specific to kwexpand/kwshrink vs kwfiles commands

Flag kwfiles if verbose; shorten bailout code

Tighten condition for kwshrink/kwexpand test
