Revert "Merge pull request #452 from LemonBoy/terminfo-cup"
Fixes #733. The fix outlined in #452 had adverse effects for the
following reason. The code removed the restoration path that would go on
the code path from kill SIGTSTP. The problem is this: When Irssi is not
running in a controlling parent (like a shell), the TSTP will in fact be
ignored. In that case, there is no process sending a CONT either and
thus the screen state never gets restored. Luckily, the patch in #457 is
sufficient to prevent the problem in #450 (which lead to the development
of #452). To that end, we do end up with potentially calling
terminfo_cont twice but that is better than not calling it at all.
This reverts commit b1ffd5f6472584aa3966746da9728c5afefcc4ce, reversing
changes made to 9cb0419435d1ad331c1f55361a003d9682fae9a8.
