FIx for issue with default values

[remorse]

Hi! This should fix "issue 1". I'm sure there is a more succinct way to do it, but I'm not really clever enough to see it...

That's fine if the empty parameter is guaranteed to be sent, rather than omitted entirely. I remember having the opposite problem a while ago, where the defaults were being used for values which the user had cleared in the form. I don't remember whether that was CGI or StickyForms though, nor how or whether I managed to fix it.

I'll have to do some reading and experimentation.

[remorse]

According to the spec (which I quoted in issue 1), undef means that the variable was not passed at all; if it is empty, CGI will return an empty string... I don't know if that helps or not...

[pmh1wheel]

Sorry, I was talking about the browser, not CGI.pm. If the user clears a
field on a form, will the browser always send an empty parameter?

[remorse]

So far, in my current testing, yes, but I haven't been exhaustive about this yet...

[pmh1wheel]

Sorry if I appear to be ignoring this. My time is being sucked away by other things at the moment, but I haven't forgotten about it

[remorse]

No worries -- I know exactly how that goes...
