Treat SOS and PM terminal escape sequences like APC

Browse Source 
This is a cherry-pick of Stefan Tauner's patch from main, but without
my followup refactoring, since the refactoring seemed to me to have a
(small but easily avoidable) chance of introducing a bug in 0.83.

The only downside of the original patch is that it contains a variable
name telling a lie: 'osc_is_apc' should really read 'this isn't an OSC
but one of APC, SOS and PM'. But we don't actually treat those three
things differently, so the functionality is fine.

(cherry picked from commit b6b95f23e5)
