Description Christian Persch 2017-12-10 20:46:39 UTC 
In set_scrolling_region() we bail out if the region is < 2 lines, with a comment saying this is xterm behaviour.

However, kitty's screen.c says:
// Even though VT102 and VT220 require DECSTBM to ignore regions
// of width less than 2, some programs (like aptitude for example)
// rely on it. Practicality beats purity.

However we haven't received any report about aptitude not working correctly on vte...

konsole also has doesn't require at least 2 lines, and in fact I don't see that check in xterm either.

So probably we should drop this extra condition.

Seems I misinterpreted the xterm code; no changes to vte required after all.
