The working tree contains a list of revisions that have been merged but
not yet committed. These revisions will be included as additional parents
of the next commit. Normally, using revert clears that list as well as
reverting the files. If any files are specified, revert leaves the list
of uncommitted merges alone and reverts only the files. Use ``bzr revert
.`` in the tree root to revert all files but keep the recorded merges,
and ``bzr revert --forget-merges`` to clear the pending merge list without
reverting any files.
