kwdemo is demo internally; rearrange code

Typo in kwdemo output

Fix ui inheritance for kwdemo kwdemo config changes had no effect if keyword.py was not in hgext. For backwards compatibility we use repo.ui in reposetup, so inside kwdemo the temporary _repo.ui has to obtain the paramters.

Add kwdemo command as online config help Shorten "hg help keyword" output accordingly. Mention utc date template filter in extension help.

wwread and wwrite methods for expansion in working dir

Cosmetic changes for overwrite condition, single quotes

Change ui inheritance to stay compatible with recent Hg Needed for rollback on interrupted commit.

Handle rename and copy properly Touching a renamed or copied file made it seem modified.

filectx does not need filelog; more nokwcommands Improve docs.

Revert to kwrepo methods (self) inside class kwrepo

Pass filelog, not kwfilelog, to kwtemplater.expand/context.filectx

More nokwcommands: add, remove, addremove

Remove unused path attribute from kwfilelog

Reduce use of kwrepo methods Use repo and ui arguments from reposetup where possible. kwfmatcher doesn't need to be an attribute to repo.

reverse logic for detection of excluding commands Exclude all "outgoing" commands. rollback does not change working dir. incoming -p does not expand anyway. Revert ui -> repo.ui for backwards compatibiliy in reposetup.

Obey Mercurial line continuation convention
