extensions: remove import rendered unnecessary by
e4e22a310b62
extensions: improve the consistency of synopses
Trying as much as possible to consistently:
- use a present tense predicate followed by a direct object
- verb referring directly to the functionality provided
(ie. not "add command that does this" but simple "do that")
- keep simple and to the point, leaving details for the long help
(width is tight, possibly even more so for translations)
Thanks to timeless, Martin Geisler, Rafael Villar Burke, Dan Villiom
Podlaski Christiansen and others for the helpful suggestions.
bookmarks: help improvements
- bookmarks are obviously Mercurial's, no need to specify it
- more explicit about the behavior without track.current
- typos
Note: the extension's help is shadowed by that of the command
of the same name and as such will never appear to the user.
Thanks to timeless for the fixes.
