Ah, but $ScriptUrl *does* change, so you have to set $PageLogoUrl
before you include wikifarm-pre.php -- the 'SDV' means that if it's 
already set, it won't be over-written.

To make the farm work without modifying pmwiki itself, we change 
$ScriptUrl to "$ScriptUrl/~Fieldname"  -- there may be a better way,
but we couldn't think of one.

This means we have to set $PageLogoFmt *before* we mess with
$ScriptUrl, otherwise the logo points to the home page of the
current field, instead of the home page in the common area.

Of course in some cases, this might be a desirable behaviour,
in which case you can redeclare $PageLogoFmt after including 
wikifarm-pre.php. In our situation, we want the logo always to
point to the common home page of the wiki.
