Patch 9.0.1039

[Bram Moolenaar]

Problem: Using a <Cmd> mapping CmdlineChanged may be triggered twice.
Solution: Count the number of times CmdlineChanged is triggered and avoid
doing it twice. (closes #116820

We do routines and chorus scenes
With footwork impeccable.

We eat ham and jam and spam a lot.
