There was a time when people knew what to expect from a Bourne shell,
and what from a POSIX shell. I guess.

Fine with me, but why didn't you use singular here, too? And why
"considered"?
Arithmetic expansion is not portable as some shells (most
notably Solaris 10 @command{/bin/sh}) don't support it.
I mean, two paragraphs up of your patch site, it already says:

Cheers,
Ralf
