PmWiki doesn't determine this -- it depends on how your browser chooses to
send the 'action' control, and how PHP elects to convert that into 
$_GET['action'].  PmWiki just takes any value of $_GET['action'] that it
happens to receive and uses that.

At any rate, there are no plans for PmWiki to change the way it handles
actions in the 2.x series.

Perhaps use a control name other than 'action' and check for it in 
config.php -- if it exists then use that to (re)set the $action
variable that PmWiki uses.

Or, create a custom form tag that uses exactly the action you want.
