  30 Push one or more patches (defaulting to the first unapplied one) onto
  31 the stack. The 'push' operation allows patch reordering by commuting
  32 them with the three-way merge algorithm. If the result of the 'push'
  33 operation is not acceptable or if there are too many conflicts, the
  34 '--undo' option can be used to revert the last pushed patch. Conflicts
  35 raised during the push operation have to be fixed and the 'resolved'
  36 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."""
