Generally, posting a URL in isolation is not going to get you as good an
answer as actually posting the question contained at that URL, as not
everyone is willing to go chase down the extra information that was not
already in the email.  Posting the URL _in addition_ to the question is
fine, but it's best to ask the question directly.

Reading that page, it looks like the original poster (named "sid_com" -
is that you? And if not, why are you reposting someone else's
questions?) wants to alter the passed-in parameters in $@ to remove
trailing slashes for subsequent use by rsync:

This thread has evolved on the bash mailing list in spite of not having
the original question at hand; maybe the next time you try to forward a
question, you can help everyone involved by giving better details.
