No need to read changelog in show(); node mandatory arg for expand()

Just re-bin the node kwarg of the hook, instead of using changelog

Same as for hardcoded branch: omit hooktype test, return w/o explicit value

Omit hook test; return w/o explicit value (==False)

No clumsy setting of node in kwfilelog.add, pass as kwarg

Expansion entirely in kwfilectx.expand()

Implement custom keyword map templates in hgrc More expensive than hardcoded keywords. But, of course, more flexible. ATM templates can only be set in hgrc, and perhaps this is enough.

Indentation cosmetics

Clean keyword arg assignment in kwfilelog.add; rename utc() to utcdate()

Init context.filectx only once per file with class kwfilectx This way context.filectx is not initialized for every keyword match.

Added tag very_cvs for changeset 2e930f842242

Very CVS-like format

Functions instead of variables in kwexpand() Should be slightly faster as filectx is asked only on demand.

Module detection cleaner and more reliable Stolen from mercurial.lsprof

Only extend sys.path if needed
