From: Todd C. Miller <Todd.Miller@courtesan.com>
The following ksh diff needs wide testing.  It does the following:
 1) proper error message for bad substitution.
    Before:
        $ echo ${a[@]:foo}
        ksh: : bad substitution
    After:
        $ echo ${a[@]:foo}
        ksh: ${a[@]:foo}: bad substitution
 2) fix a core dump for "echo ${a[@]:?foo}".
 3) fix a use-after-free bug (from otto@)
