Implement kwcat command

Make kwtemplater kwrepo attribute instead of global variable

Refactor overriding wread, wwrite, wwritedata repo methods - restrict consistently to reading/writing in working dir - no cludgy sys.argv parsing anymore Eases collaboration with other extensions, or external tools like TortoiseHg. Changes in behaviour: - hg cat does not expand; will be implemented with new kwcat command - no expansion in web /display/, only in downloaded archives Thanks to Jesse Glick for inciting this approach.

(0.9.2compat) fix external hook as in default branch

Return silently when external command triggers error - make hook accept hg command as string or as function object. - intercept dispatch.ParseError as well. Kudos to Steve Borho (TortoiseHg) for testing and debugging.

(0.9.2compat) implement external call handle and hook

Implement handle and hook for external callers Allows external callers that do not use the command line to pass current hg command to keyword extension. This implementation might change in the future, if wrapping of patch.diff is possible to the effect of avoiding external handles.

Get changes from default branch; update test output

Detect restricted commands thru variable

Improve use of dictionaries - iteritems() where we do iter over dicts' items - store commithooks in dictionary (safe, as hook.hook() sorts before execution)

bugfix: avoid expansion with qfold

Prefer item in dict over dict.has_key(item) Message-ID: <4792DB2A.7050909@serpentine.com>

(0.9.2compat) get mq support, improved diff output from default branch Reimplement _parse wrapper obtain diff options.

Add a very simple mq test
