hghave: fix has_bzr() to not try to import RevisionSpec as module Since RevisionSpec isn't a module, "import bzrlib.revisionspec.RevisionSpec" would always raise ImportError.

update: label bookmark name in message We label bookmark name as such in various messages. This will help them to standout (or at least give the user the option to make them stand out). We use a distinct label for the 'active' bookmark, this can help users to catch bookmark operation affecting their working copy.

discovery: explicitly check for None in outgoing init f09d0004481c introduced default params for discovery.outgoing(), but it used a falsy check instead of an explicit check for None. The result is that callers that passed in an empty list would have that list overridden by the defaults, which is not the expected behavior. This was discovered by changes to the test-pushrebase.t test in Facebook's repository of mercurial extensions.

import: report directory-relative paths in error messages (issue5224) Import uses paths relative to the root of the repository, so when user imports patch with paths relative to the current working directory import aborts with 'unable to find file for patching'. This patch improves this situation by warning the user that paths are relative to the root of repository when patching fails.

commands: remove unecessary copying of list in graft()

revset: do not partial-match operator and function names in optimize() It was error-prone, and actually there was a typo, s/ancestorspec/ancestor/.

revset: remove false condition to process 'negate' operator 'negate' is mapped to 'string' at the above clause.

revset: make optimize() reject unknown operators This should have caught the bug of 'keyvalue' operator fixed at 5004ef47f437. The catch-all pattern is useless since optimize() should be aware of all known operators.

help: show content for explicitly disabled extension (issue5228)

obsolete: fix minor module documentation issues

debugextensions: hide "ships-with-hg-core" magic string (BC) Since we have "bundled" flag, we no longer need to rephrase "ships-with-hg-core" to show as "internal".

debugextensions: show ships-with-hg-core state as a separate field This is less magical than rephrasing ships-with-hg-core as internal, and we can distinguish "internal" liar. "tested with: internal" will be hidden by the next patch.
