purge: add options for deleting only files or only directories

shelve: accept '--edit' like other commands creating new changeset After this patch, users can invoke editor for the commit message by '--edit' option regardless of '--message'.

shelve: refactor option combination check to easily add new ones Before this patch, the name of a newly added option had to be added into each string that was passed to the "checkopt()" internal function: these are white-space-separated list of un-acceptable option names (= "black list" for the specified "opt"). This new option had to be added into multiple strings because each option could belong to only one action of "create", "cleanup", "delete" or "list". In addition to this redundancy, each string passed to "checkopt()" was already too long to include a new one. This patch refactors option combination check to make it easier to add a new option in a subsequent patch. New "checkopt()" only takes one action ("cleanup", "delete" or "list"), and checks whether all explicitly activated options are allowed for it or not (if specified action is activated in "opts"). The "date" entry is listed in "allowables", but commented out, because: - "date" shouldn't be checked for test checking "date" causes unexpected failure of "test-shelve.t", because "run-test.py" puts "[default] shelve = --date '0 0'" into hgrc. - explicitly listing it can advertise that ignoring it is intentional This patch doesn't choose "white list" for the specified "opt", to avoid treating global options.

test-extension: add check for 'hg version -v' listing enabled extensions

version: show enabled extensions (issue4209) This code is based by hg-versions extension (GPLv2) by Markus Zapke-Gruendemann <info@keimlink.de> http://mercurial.selenic.com/wiki/VersionsExtension

strip: remove bookmarks after strip succeed (issue4295) In case we have revs to strip, delete the bookmark after the strip succeeds, not beforehand as we might still abort due to dirty working directory, etc.

templater: introduce word function This function allows returning only the nth "word" from a string. By default a string is split as by Python's split() function default, but an optional third parameter can also override what string the string is split by.

committablectx: move __contains__ into workingctx This was mistakenly moved from workingctx to committablectx in 9d56a3359011. Since the method is querying the dirstate, the only logical place is for it to reside is in workingctx.

memctx: explicitly set substate to None In d2743be1bb06, memctx was changed to inherit from committablectx, this in turn added the 'substate' property to memctx. It turns out that the newcommitphase method tested for this property: def newcommitphase(ui, ctx): commitphase = phases.newcommitphase(ui) substate = getattr(ctx, "substate", None) if not substate: return commitphase Currently, memctx isn't ready to handle substates, nor removed files, so we explicitly must set substate=None to get the old behavior back. In the future, we can decide how memctx should play with substate. For now, this fixes third-party extensions and some internal code dealing with subrepos.
