chunkbuffer: use for/else to detect end of iteration

changegroup*(): use enumerate when possible

changegroupsubset(): with the fix, prune() is actually useful in the testsuite

test-permissions: echo commands to make output readable

changegroupsubset: simplify knownheads/has_cl_set computation

changegroupsubset(): ancestors() is not inclusive, we need to remove the "heads"

changegroupsubset(): move comment at the right place

changegroupsubset(): refactor the prune() functions

help: make helptable a list instead of a tuple The table should always have been a list so that extensions can append their own help topics -- hgsubversion would like to do this now.

test-command-template: test 'children' template keyword

templates: 'children' keyword The template keyword 'parents' is already present and this just provides the complimentary template keyword.

changegroupsubset(): change variable names, simplify lookup logic

changegroup(): used "linkrev" instead of "revlink"

fix comment

revset: fix ancestor subset handling (issue2298)

hgwebdir: use template paths configured in the hgrc (issue2281)

changegroup*(): use set instead of dict

Merge with stable

bash/zsh completion: use HGPLAIN when invoking hg (issue2297)

patch: fix extract() docstring, it returns branch as well

merge with stable

doc: remove has_key usage in hgmanpage

gendoc: remove callable usage (check-code)

bookmarks: rewrite _bookmarks method documentation

init: create target directory recursively Subrepos with relative paths must often be cloned to locations deep in the directory structure. This allows clone over ssh (init+push) work.

doc: make sure we use our own code for generating man pages docutils would in some situations pick up its own manpage.py instead of doc/manpage.py. Renaming to hgmanpage.py makes it less ambiguous.

transplant: crash if repo.commit() finds nothing to commit (makes issue2135, issue2264 more obvious, but does nothing to fix either one) This seems to happen in two distinct cases: * patch.patch() claims success but changes nothing (e.g. the transplanted changeset adds an empty file that already exists) * patch.patch() makes changes, but repo.status() fails to report them Both of these seem like bugs in other parts of Mercurial, so arguably it's not transplant's job to detect the failure to commit. However: * detecting the problem as soon as possible is desirable * it prevents a more obscure crash later, in transplants.write() * there might be other lurking (or future) bugs that cause repo.commit() to do nothing Also, in the case of issue2264 (source changesets silently dropped by transplant), the only way to spot the problem currently is the crash in transplants.write(). Failure to transplant a patch should abort immediately, whether it's user error (patch does not apply) or a Mercurial bug (e.g. repo.status() failing to report changes).

mq: cleanup status if applied mq is stripped (issue1881) stripping of applied mq patches leads to wrong state recorded in status file. find all mq patches that will be affected and clean up status file before strip.
