Subject: [PATCH] suspension: fake a SIGWINCH when coming back out of the
background
When receiving a SIGCONT, don't call regenerate_screen() directly
but act as if a SIGWINCH occurred. Also insert a dummy key, and
thus let the relevant input routine redraw the relevant subwindows.
Use KEY_F0 as the dummy key, as both Ncurses and Slang know it, and
it should normally do nothing at all.
This fixes https://savannah.gnu.org/bugs/?51124.
