It seems that we should set up a list of shell implementations that
should be looked at when cheking for new POSIX ideas.

First, I believe that "yash" and "posh" should not be in that list
because these implementations are too buggy or have unexplained
deviations. "yash" is able to run configure, but "posh" is so buggy
that it will not run a "configure" script at all.

So a useful list should have:

bash
bosh
dash
mksh
ksh88
ksh93

I am not sure whether we should add "zsh" to this list as zsh
by default implements many intentional deviations to the standard.

Note that I know of no way of doing zsh / POSIX related tests
that work except for copying zsh to /tmp/sh and then test with
/tmp/sh, as I could not find a better way to make zsh compliant
enough to be able to run a "configure" script.

It would be nice, if reports in future would check the shell
implementations from the agreed list.
