It's the same issue: when SIGWINCH is received, read() is restarted
automatically (ERESTARTSYS) and thus bash isn't calling the ioctl(0,
TIOCGWINSZ, ) until readline receives the next character, at which point
the full line is rewritten.

(and yes, it seems desirable not to wait for next character)
