commit 528dedf3fe0051922cb1a66083fce16ac0057753
from: Stefan Sperling <stsp@stsp.name>
date: Mon Aug 30 19:46:56 2021 UTC

make tog block other keys except Backspace after End/G is pressed

This should avoid unexpected behaviour resulting from unrelated
key presses messing with the log view's state variables.

Pointed out by tracey, and also discussed with jasper.
ok tracey
