in thread what's the difference between "$@" and ${1+"$@"}

Aha! Now it makes sense. Thanks everyone, especially Merlin, for your imparted wisdom...

And I finally found a web page that discusses this, with some good background detail.

As an interesting side note, I wonder if anyone knows how to give this string (${1+"$@"}) to Google's search engine. As is, it doesn't work. I tried single-quoting it, and it still doesn't work.

Cadphile...
