I placed a link on the recipe page to your message at the list archive.

I cannot suggest that you or someone else take over the maintenance, 
because the author has not released the recipe under a license allowing 
modification and redistribution.

There is no "var" entry in the core, so ">var" would not work since 
PmWiki 2.2.0-beta46 (2007-05-19). I see that the last version of the 
recipe is from 2007-03-07 which is earlier.

There is a markup rule "{$var}" early in the processing, maybe the 
author meant to use ">{$var}". Or maybe there is another recipe that 
defines a "var" entry.

Previously, the markup rules with undefined "$when" arguments were 
processed but I'm not sure when -- in this case it appears that it would 
be processed at the beginning.

It depends if the markup rule outputs more PmWiki markup to be processed 
at a later point: in that case it does and needs to be processed before 
the other markup rules (links), or the function needs to call PRR() to 
restart the processing.
