rebase: enable multidest by default This was intended to be done by D470. But there was a minor documentation issue. The feature is quite usable now so it gets formally documented and enabled. There is no behavior change for people not using the `SRC` or `ALLSRC` in rebase destination revset. .. feature:: Rebase with different destination per source revision Previously, rebase only supports one unique destination. Now ``SRC`` and ``ALLSRC`` can be used in rebase destination revset to precisely define destination per each individual source revision. For example, the following command could move some orphaned changesets to reasonable new places so they become no longer orphaned:: hg rebase -r 'orphan()-obsolete()' -d 'max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::)' Differential Revision: https://phab.mercurial-scm.org/D1063

     Rebase will destroy original changesets unless you use ``--keep``.
     It will also move your bookmarks (even if you do).
