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. | |
37 | ||

38 | The command also notifies when the patch becomes empty (fully merged |
39 | upstream) or is modified (three-way merged) by the 'push' operation.""" | |
