journal: new experimental extension
Records bookmark locations and shows you where bookmarks were located in the
past.
This is the first in a planned series of locations to be recorded; a future
patch will add working copy (dirstate) tracking, and remote bookmarks will be
supported as well, so the journal storage format should be fairly generic to
support those use-cases.
