Hi,

Foot has never supported neither 132-column mode, nor smooth 
scrolling. It did however recognize the escape sequences, and 
logged an "unimplemented" warning. It also implemented certain 
side-effects of DECCOLM (erase screen, home cursor). This applied 
for foot <= 1.13.1.

It is now being changed, and we're removing *all* support for 
DECCOLM+DECSCLM completely. Warnings and side-effects. This is 
being done in https://codeberg.org/dnkl/foot/pulls/1268.

As part of that, we'd like to see the DECRSTs of these two being 
removed from foot's terminfo. Please see attached patch.

Thanks,
Daniel (I'm not subscribed)
