strip: drop -b/--backup option (BC) This option had very limited utility and counterintuitive behavior and collided unfortunately with the much later -B option. Normally we would no-op such a feature so as to avoid annoying existing scripts. However, we have to weigh that against the silent misbehavior that results when users mistakenly intended to use -B: because -b takes no arg, the bookmark gets interpreted as a normal revision, and gets stripped without removing the associated bookmark, while also not backing up the revision in question. A no-op behavior or warning would only remove the latter half of the misadventure. The only users I can find of this feature were using it in error and have since stopped. The few (if any) remaining users of this feature would be better served by --no-backup.

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.
