Ok, that makes sense.  I was under the impression that 30 is too small
but you're right that it could (should?) stay the same.

Alright, so what about this new version of the patch?  FWIW, I have
tested it lightly and the only time the keybinding alignment is off is
when menu entry is quite long and we needed the 2 spaces separation with
the keybinding.
