Move backwards compatible commit fork into private kwrepo function

Remove spurious NameError checking for locks Overriding commit sets them to None by default already.

Clean up backwards compatibility Overriding findcmd is obsolete. Override _parse at top. Prefix overridden functions with underbar.

cmdutil.parse moves to dispatch._parse; use fancyopts bugfix Copy fancyopts from 88803a69b24a as _fancyopts to make argument parsing reliable.

Removed files are detected by _weedcandidates, no need for status call

Document revision that fixed fancyopts

Test "hg diff --rev", update _getcmd comment (backwards compatibility)

Test that pattern does not span more than 1 line

Shorten template setup

ui inheritance does not need to be fiddled with anymore Backwards compatibility tests work with at least 0.9.2

Include MANIFEST.in in dist; hgignore MANIFEST

setup: add url, reformat

test: use grep -v instead of sed to delete lines

try for dirstate.update instead of hasattr
