Responding on the list, it is better to keep the
technical stuff here so that others may benefit/help.

You should be able to extend the method to set
$PreviousGroup and $PreviousName if you'd like. To
get those values inside of the PmWiki function you may
need to use something like:
$group = FmtPageName('$Group', $pagename);
$name = FmtPageName('$Name', $pagename);
see this page for a reference:
http://pmwiki.org/wiki/PmWiki/FmtPageName
This could then become (untested):
$qf .= $qf ? "&":"?" .
FmtPageName('PreviousPage=$FullName&PreviousGroup=$Group&
PreviousName=$Name");
Then don't forget to define access to those GET
variables like you did for PreviousPage,
