thanks
I can confirm that this behaviour is happening in ksh93, (though I
personally cannot confirm it is not in ksh88).
I looked in the POSIX spec
(http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_05_01
), and I could not see a clear definition of expected behaviour.
The source contains a file, src/cmd/ksh93/COMPATIBILITY, supposedly
listing differences between 88 and 93. It does not list this one, but it
does say there could be more.
I don't see this as a big issue because you can find out equivalent
information since the information needed to avoid accessing undefined
positional variables is available in $*, $#, etc.
