tweaks: check the multiline regexes only for Delete and Backspace

The checking for all functions that are marked as not-okay-for-view-mode
was excessive and unneeded.  It had been inherited from commit d47d8cd4
from thirteen years ago, and was never verified for correctness.

This addresses the main part of https://savannah.gnu.org/bugs/?62903.
