[pmwiki-users] Maintaining recipes that require non-relative urls ({*$var})

[Pico]

When relative urls were introduced there was an acknowledgment that 
relative links will "break" skins, such as Triad?  At the time I assumed 
that the reference was simply to the fact that the distributed pages 
would need to change various links from {$var} to {*$var}, but now I am 
realizing that the issue may be bigger than that when it comes to 
maintaining and distributing recipes that will work with all recent 
various versions of PmWiki: If you "fix" certain links by changing them 
from {$var} to {*$var}, what will those new links do on prior versions 
of PmWiki (2.1.26 and earlier)?  Since I no longer have any such 
versions installed, I missed the opportunity to test that.

I assume that the new (*$var) form will not be properly rendered on 
2.1.26 and earlier and thus, skins such as Triad that are distributed 
with supporting pages that contain edit links will need some way to 
provide different markup for older and newer versions of PmWiki.  Aside 
from maintaining and distributing separate recipe files, I assume that 
this could be handled with conditionals that test the version number of 
PmWiki.  Are there problems with that approach?  Is there a better way?
