Spurious audit trail entries from unchanged multitext field

[Robert Inder]

   I've also put this in the GNATS database at bugs.gnu.org...
   I'm nto sure whether that is "belt and braces" or pointless
   repetition...

I have configured a multitext field to be audit trailed, and I
am getting spurious audit trail entries when I use gnatsweb.

field "Contact" {
    description "What did we last talk about"
    multitext {
        default ""
    }
    on-change {
        add-audit-trail
    }
}

Simply editing the PR, then submitting the form unchanged
adds an audit trail entry.

Browser is Mozilla on FreeBSD.  Gnats and Gnatsweb are also running
on FreeBSD.

My bet is that the problem is caused by the way white space
is being handled: something (the browser) is padding a
short string up to the size of the HTML textarea, and this
is not being stripped.

This is going to be causing me minor grief on a daily basis.

I could flounder around and try to fix it However, I notice that
gnatsweb.pl is already doing some re-formatting to multitext fields,
but since I don't know exactly why, I could well break something.  

So I suspect someone who knew what was going on in there could
probably do it a lot faster than me...

Robert.
