This probably has something to do with the special-casing around wgetch()
for signals handled by the "trap" command.  See the big comment in
Src/Modules/curses.c lines 1073-1103.

It may be problematic to mix curses with the generic signal handling in
the main shell.  We may need to swap in a SIGWINCH handler wrapper while
the curses UI is active, and restore the main handler when leaving it.

} my first input call.

There's probably some state that needs to be cleared on entry to
zccmd_input() so that curses doesn't see something left over from the
previous signal.  Unfortunately I don't know what that would be.
