I'm afraid these changes break SIGWINCH handling of child processes.

If you start an editor or mail-reader or terminal-multiplexer (or
whatever really), that child will not react to any terminal-resizes

It took a while to find out, why this:


didn't trigger in shells inside the terminal-multiplexer I use, but does
trigger in a naked xterm without multiplexer. The fact that the terminal
multiplexer itself didn't react to SIGWINCHes anymore steered me into
zsh's direction (well, not directly but eventually).

Building a version of the shell before these changes¹ makes everything
work again.  Sorry to be the bearer of bad news. ;)

Regards, Frank
