Pegs: clear ui->cur_jumping on undo or redo.

Fixes an assertion failure in which you move the keyboard cursor to a
peg, press Enter to indicate that you're about to jump it to
somewhere, and then instead execute an undo or redo action which
replaces the peg with a hole. Thanks to Vitaly Ostrosablin for the
report.
