We check if the current bookmark is set to the first parent of the
dirstate. Is this the case we move the bookmark to most recent revision
on the current branch (where hg update will update you to).
Since bookmarks are no longer merged with repo.tags() as of
8e2d23f4bd25, they don't show up in `hg id` as they used to. This adds
them back into the summary that `hg id` prints, and adds a
-B/--bookmarks flag alongside the -t/--tags and -b/--branch options.
Note this introduces a slight backwards-incompatibility: the summary
printed by `hg id` now separates bookmarks from tags with a space, as
seen below, instead of running it into the tags list.
Default summary output:
$ hg id
db815d6d32e6 tip/tag1 bm1/bm2
Output with --bookmarks:
$ hg id --bookmarks
bm1 bm2
See also 5672c9e8202d which adds bookmarks back into `hg summary`.
hg bookmark -r ancestorrev X will not mark X as the current bookmark anymore.
If you want to point a bookmark to a ancestor rev you will use hg update to
move to it. This will set the current bookmark.
We restrict : to 1. make it easer to convert bookmarks to git branches,
2. use : later for a syntax to push a local bookmark to a remote bookmark
of a different name. \0, \n, \r are fobbidden they are used to separate
bookmarks in the bookmark file.
This change breaks backward compatbility as ':' was an allowed character in
previous versions.
