dirs.addpath: rework algorithm to search forward This improves performance because it uses strchr rather than a loop. For LLVM/clang version "Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)" on OS X, for a repo with over 200,000 files, this improves perfdirs from 0.248 seconds to 0.230 (7.3%) For gcc 4.4.6 on Linux, for a test repo with over 500,000 files, this improves perfdirs from 0.704 seconds to 0.658 (6.5%).

changeset_printer: use changectx to get status tuple log.parents() can't handle wdir() revision. Because repo.status() creates ctx objects, there would be no benefit to get parent node from changelog.

changeset_printer: replace _meaningful_parentrevs() by changeset_templater's Because changeset_printer needs pctx object anyway, there would be no benefit to avoid creation of pctx in _meaningful_parentrevs().

changeset_printer: use context objects consistently to show parents This prepares for merging changeset_printer._maningful_parentrevs() with changeset_templater's.

children: don't pass filectx to displayer displayer doesn't want a fctx but a ctx. It failed with -Tdefault template. Traceback (most recent call last): ... File "mercurial/templatekw.py", line 212, in showbookmarks bookmarks = args['ctx'].bookmarks() AttributeError: 'filectx' object has no attribute 'bookmarks'

verify: add a note about a paleo-bug In the very early days of hg, it was possible to commit /dev/null because our patch importer was too simple. Repos from this era may still exist, add a note about why we ignore this name.

cmdutil: remove some excess vertical whitespace

revert: move calculation of targetsubs earlier

shelve: add interactive mode This allows us to shelve selectively part of the changes of the workdir

shelve: add interactive mode command line option

record: change return value of recording code It makes it easier to include interactive mode to more commands that require to get a reference to the newly created node

revert: fix --interactive on local modification (issue4576) We were moving files during the backup phase and it was incompatible with the way record/crecord is working
