mouse: do not offset the shortcuts by 'margin' when using --linenumbers

Browse Source 
The bottom window (the prompt bar and the shortcuts) does not shift
its position when line numbers are active, so mouse clicks in this
window should be not be compensated for the line-numbers margin.

This fixes https://savannah.gnu.org/bugs/?59749.
Indirectly-reported-by: ObeliX <ObeliX-@gmx.de>

Bug existed since version 2.7.0, since line numbers were introduced.
