Detailed test of kwexpand/kwshrink w/ file arguments

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

Underscore prefixes only for names at top level, or compatibility wrappers

Count keywords in a customized kwfilelog read method

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.

kwfiles notifies if there are no files configured for expansion

Bail out earlier in overwrite commands if repo has changes

Make kwfmatcher an ui attribute Thus kw commands do not weed candidates twice.

Unlowercase command help

Test kwfiles working context

Determine kwfiles on workingctx Added but not yet committed files should be shown. Removed but not yet committed files should not be shown.

test: use grep instead of grep -F

Test if debug flag influences expansion

Turn off debug while expanding We don't need templates like file_add etc. as keywords a file specific. Turning off debug avoids accidental expansion of such templates. As a side effect it speeds up expansion when running hg --debug. Functionality of _ctxnode now in new _substitute function.
