I don't like the idea of just adding a hidden field in the form for
three reasons:

1) It seems to be an unclean way of doing things, overriding
one field entry with another one. I don't know if it is standardized,
that every browser sends the fields on the post-request in the exact
order in which they occur in the HTML page. I don't know if PHP
always takes the last value of the field. Seems to be something that
might work, but may also fail.
This was actually the reason, why I added the "target=" option in the
first place.

2) This does not work it you use CleanUrls. At least that's
what I figure. I you look into the target URLs of the e.g.
the edit form on pmwiki.org, you'll see, that the pagename
is also part of the target-Atribute of the <form ...> element.

I'd like to be corrected, if I'm wrong, but this seems to be
essential for $_POST-ing form data to a page. I can't say I fully
understand why, but when I tried to ...

Well, that's weird, it seems to work... Mhm, I don't understand...
It didn't work, when the target was set to $ScriptUrl...

3) In PmWiki it is common that a link to [[SomePage]] leads to
CurrentGroup.SomePage. If a form allows you to enter a page name
(such as the (:newpagebox:) for example, than this should have the
same behavior in my oppinion.

Alright, it seems to work, so there is no urgent need to do anything 
about it.

I am impressed, anyhow.
