Open mouth, insert foot: That should be ${1-"$@"}, which indeed breaks
under Linux's bash. However, ${1+"$@"} seems to work fine under that
bash...
Interestingly enough, this also shows up under Solaris bash from the
gnu locker -- presumably this is a generic bash bug?

Well, it worked on all the Athena platforms :-)
I've tested the + version under Solaris 2.3, Linux 1.1.64 (I've no
idea what dist...), AIX whateveritis, and--*ouch*. It seems that
under SunOS 4.1.3 and under Ultrix, and probably other good
BSD children,
When the script is called as:
script "" foo
It is interpreted as
script foo
Sigh...back to the drawing board...
