30 Push a patch (defaulting to the first unapplied one) or range of
31 patches to the stack. The 'push' operation allows patch reordering by
32 commuting them with the three-way merge algorithm. If the result of
33 the 'push' operation is not acceptable or if there are too many
34 conflicts, the '--undo' option can be used to revert the patch and the
35 tree to the state before the operation. Conflicts raised during the
36 push operation have to be fixed and the 'resolved' command run.
38 The 'push' command also notifies when the patch becomes empty after
39 the merge operation (i.e. it was fully merged upstream)."""
