hgweb: support very simple caching model (issue1845)

tests: extend get-with-headers to support cache testing

tests: fix test output for test-hgweb-no* tests

tests: rename test for better grouping

check-code: fix ternary expression introduced in 1ef9b0b5efec

bisect: warn about ending on a merge with only one side marked

bisect: allow revsets in addition to single revs (issue2360)

subrepos: add function for iterating over ctx subrepos

subrepos: handle modified but uncommitted .hgsub

localrepo: check nested repos against working directory This checks against what is really in the filesystem, including subrepositories that have been added to .hgsub but not yet committed.

add: clarify that repo[None].add returns rejected filenames

merge with stable

store: Removed extra space in _data list

verify: fix "missing revlog!" errors for revlog format v0 and add test With revlog format v0 the .d files are empty if the only revision stored is an empty file. Since Mercurial can no longer create format v0 repositories, but still use it, add a script which creates a repository with a single empty file. This can be used in other tests if wanted.

zsh completion: bookmarks support

zsh completion: patchbomb support

diff: recurse into subrepositories with --subrepos/-S flag

status: recurse into subrepositories with --subrepos/-S flag

match: add narrowmatcher class This class can be used to adapt an existing match object to a new match object that only cares about paths within a certain subdirectory.

cmdutil: use repo.auditor when constructing match object This gives the repository control over which nested repository paths that should be allowed via the custom path auditor. Since paths into subrepositories are now allowed, dirstate.walk must now filter away more paths than before.

match: accept auditor argument This is used when normalizing filenames and patterns.

localrepo: add auditor attribute which knows about subrepos

tests: remove unneeded -u flags

merge with stable

tests: unify test-empty-file

tests: unify test-empty-dir

tests: unify test-dispatch

tests: remove unneeded -d flags Many tests fixed the commit date of their changesets at '1000000 0' or similar. However testing with "Mon Jan 12 13:46:40 1970 +0000" is not better than testing with "Thu Jan 01 00:00:00 1970 +0000", which is the default run-tests.py installs. Removing the unnecessary flag removes some clutter and will hopefully make it clearer what the tests are really trying to test. Some tests did not even change their output when the dates were changed, in which case the -d flag was truly irrelevant. Dates used in sequence (such as '0 0', '1 0', etc...) were left alone since they may make the test easier to understand.

test-merge5: removed unnecessary parts of test - no need to initialize a new directory - no need to fix the commit time, already done by run-tests - no need to exit 0, use exit code from hg instead - better spacing around comments

test-merge5: ensure updating to tip across branches is tested When doing "hg update" across branches (without any revision specified), hg will abort and ask the user to merge or do hg update -c. This tests for that error.
