Ignore consecutive identical statements in history

[friedFat]

Coming from mksh, when debugging a programm I'd compile it and run it a few times.
So id first need to do make foo and then maybe 5x ./foo to e.g test if the sigterm works. As mksh only saves ./foo once, the make-command is only 2 up keys away.
In yash however, the consecutive identical ./foo calls are saved, so I need to use the arrow keys 6 times to recompile.

The problem: yash saves consecutive identical commands in the history
The solution: don't save them

Try defining the HISTRMDUP variable.
