[dev] [st][patch] Fix segfault when pressing PrintScr without a selection

[Rafa Garcia Gallego]

Hi,

Attached is a silly patch to prevent a segmentation fault in st when
you accidentally press PrintScr with no text selected.

BTW does anybody use this with a plumber? Care to explain the details?

BR,
Rafa
