Subject: [PATCH] Fix inconsistent backspace behavior

Backspace always sends ^?. When alt (mod1) is pressed, st terminal
interpret alt+backspace as ^[^h. This inconsistent behavior is so
annoying, because backspace should always consistent, either always send
^? or else always send ^h.

This patch makes st interpret alt+backspace as ^[^? to provide
consistent backspace behavior.
