String format keyword pattern before compilation

Ignore errors when removing temp dir in kwdemo

Reduce verbosity of kwexpand/kwshrink

Make kwfilelog.cmp test reliable

Use revlog.cmp to avoid checking for rename twice

Test kwfiles command

New command "kwfiles" prints files configured for expansion

Always exclude .hgtags only .hgtags is the only tracked file that is written to just by issuing an hg command. This ensures that even a very unlikely tag like "$Id$" is processed properly.

Use Mercurial's getcwd()

Set boolean mandatory arguments directly and comment them

Avoid calling kwfmatcher twice (kwtemplater.overwrite, kwrepo.file) when overwriting _weedcandidates already checks if file is configured for keyword substitution.

Test kwshrink w/ argument while not in top level directory

Arguments to kwshrink/expand must be filtered thru canonpath

Rename README.txt to README

Move version code into setup.py getversion() is only needed by setup.py, as there is no interface to query the version of an hg extension.
