What is ksh's bigger problem with "`...\"...\"...`"?  Your previous
emails in this thread don't seem to describe it, so far I've been
of the opinion that, were it not for pdksh, this expression would be
portable.

My patch adds an example for ksh's issue with "`..."..."...`", the pdksh
reference was to avoid repeating an example for its issue with
"`...\"...\"...`" here.

Thanks,
Ralf
