it's my pleasure :-)

It really was my first intention to use it like that, but that does not 
work, cause of the way include is processed by pmwiki v1, so the contents 
is inserted as one line. This results in the way pmwiki v1 resolves the 
includes and can't be changed without implementing a second 
include-function.  (the textlines are read into an array splitted by 
superscript-2, if  [[include ...]] is processed and replaced with the text 
from the included page. The text will be inserted within the array-entry 
containing the [[include]] with the linefeeds or superscript-2 kept - 
normally they should be expanded to additional array-entries, but then you 
have to rewrite this wiki-function)

Yes I understand what you want. Another possibility would be resolving all 
includes before processing a wiki-trail-page, so all subsequent 
list-entries would be processed too. But that means to change the 
trail-implementation and add the include-function here (tried this first, too).

I decided to go another way and can recommend:

migrate to version 2 ! it's spendid. the ifgroup will not be neccessary any 
more and replaced by the much better (:If condition:) markup - you can 
define any condition by yourself ! The version is quite stable, there are 
some bugs still open (see pmwiki's PITS) but you can easily setup a 
temporary v2 wiki with the old one in the "background" to test the whole 
thing. And a "automatic" conversion-script is also included. You should 
give it a try !

If you need some help for setting up the test-wiki just mail. Or join the 
pmwiki-user maillist, I got a lot of info from the folks there.
