At present this isn't possible, but it's come up enough that I may
add this capability in the near future.

Well, e_savebutton doesn't control where the form ends up -- all
it does is generate an HTML <input type='submit' ... /> tag.
In the case of the edit form in general, it's not the form that
decides where the browser goes... because in order to save the page
the form must be sent back to PmWiki with a special "post" control
set.

What we need to see about adding is a way to tell PmWiki where to
redirect the browser once a post has occurred.

PmWiki's built-in form markup does little more than make it possible
for authors to create forms -- it was designed simply to make it
easier for administrators to create custom form interfaces to
other existing applications.  PmWiki's core doesn't itself have
any facilities for processing forms beyond the basic edit/post/upload
actions.  (There are some recipes that seem to provide this, however.)

Sort of.  If interfacing with an existing web application of some
sort, then the wiki markup can make it easy to create forms and
embed them in pages.  But if someone wants to build a new
form-based application from scratch, then yes, a bit more
knowledge about databases and transaction processing is needed.
