hgweb: remove some legacy code

keyword: avoid extra diffs when not comparing against working dir When diffing against specified revisions expanded keywords only get in the way. Update test output.

keyword: support mq; handle (q)record more gracefully mq: Ensure that expanded keywords do not make it into patches. - disable expansion when reading filelog - shrink expanded keywords when reading from working dir (wread) (q)record: Avoid additional hunks due to expanded keywords. However this is still a compromise, as keyword expansions are not updated in working directory because record should not overwrite files. Mention above shortcomings and "hg kwexpand" workaround in help and update test output. system argument parsing: Command detection might be slightly more expensive with dispatch._parse, but we will need this for improving "hg diff" output.

convert: enforce svn_source.getchanges() files unicity

localrepo: ensure files unicity in commit() (issue 714)

util: simplify unique

convert: fix invalid svn.ra.check_path() call (issue 771) The svn transport must be reparented to repository root before using check_path() with full entrypaths.

util_win32: make os_link more robust (issue 761) On mapped drives, os_link() manages to create links but nlink() does not report them.

transform a bunch of print statements to appropriate ui calls

Merge with crew

convert: document the subversion conversion model

convert: fetch less revisions when looking for a branch parent

Test subversion branches conversion

convert: make svn revision iterator interruptible

convert: fix cross-branches subversion revisions handling The "one revision belongs to one branch" assumptions is relaxed. Branch revisions are parsed down to the first branch copy encountered, older history is skipped. It means the conversion is still not satisfying when dealing with branches overwriting themselves. This issue already existed in the previous version.

convert: fix parents of last fetched svn revision
