tests: confirm that a badly documented extension doesn't cause a crash An external extension whose docstring doesn't conform to Mercurial standards used to cause crashes. Test that we omit such extensions when you do a keyword search.

bookmarks: avoid creating a nested repository during testing This helps the test to pass with hgwatchman, which would otherwise need to be taught about a nested .hg directory. hgwatchman already blacklists test-nested-repo.t which covers the actual usecase

dispatch: strip command line options like config file options Currently, whitespace in command line --config options are considered significant while whitespace in config files are not considered significant. This diff strips the leading and trailing whitespace from command line config options.

hook: for python hook ImportErrors, add note to run with --traceback I personally found it completely non-obvious that --traceback prints out stack traces for failed imports.

hook: fewer parentheses for hook load errors This matches 'hook failed' warnings. We're also going to add hints to some of the hook load errors. Without this change we'd have two pairs of parens for a single error message, which looks really cluttered.

hook: use sys.exc_info rather than the deprecated equivalents sys.exc_type etc have been deprecated since Python 1.5.

doc: describe full help document hierarchy to create a valid link in HTML For example, ":hg:`help config.default-push`" creates an invalid link to "hgrc.5.html#default-push" in HTML, but ":hg:`help config.paths.default-push`" creates a valid link to "hgrc.5.html#paths".

doc: translate from :hg:`help config.SECTION` to a valid link to hgrc.5.html Before this patch, ":hg:`help config.SECTION`" in online help text is translated to a link to "hg.1.html#config.SECTION" in HTML unintentionally. This patch translates from :hg:`help config.SECTION` in online help text to a valid link to "hgrc.5.html#SECTION" in HTML. This patch ignores element(s) under "SECTION" (e.g. "ITEM" of ":hg:`help config.SECTION.ITEM`"), because there is no way to refer directly to it in HTML, yet.

doc: translate from :hg:`help config` to a valid link to hgrc.5.html Before this patch, ":hg:`help config`" in online help text is translated to a link to "hg.1.html#config" in HTML, even though actual "hg help config" shows not help for "hg config" command but "config" help topic, and all of current ":hg:`help config`" expects the latter. This patch translates from ":hg:`help config`" in online help text to a link to "hgrc.5.html" in HTML as expected. This patch also allows ":hg:`help -c COMMAND`" style to link "hg.1.html#COMMAND" for readability.

i18n: calculate correct line number in source of messages to be translated Before this patch, line number in source of the message to be translated is wrong in hg.pot, if corresponded message is placed after ".. DIRECTIVE::", because number of lines related to such directive isn't added to variable "delta", which holds number of untranslated lines in given text. This patch always adds "2" to "delta", because text block is split into translation units by "\n\n".
