It does help with normal children (ie. the ones the shell fork()s for).
But it doesn't fix cases, in which you use `exec' to replace the shell
process with the child process.

It was mangled, but is was short enough to apply manually.

I've pushed this, because it's definitely an improvement. I tried
looking for the right position to unblock SIGWINCH for the `exec' case
in exec.c, but couldn't find it yet. Maybe someone has a more specific
idea than I do?
