Currently it breaks them.  However, if a skin or recipe wants to
use {*$var} with pre-2.2 versions of PmWiki, the easiest solution
is to just add the {*$var} markup directly:

    if ($VersionNum < 2001900) {
      Markup('{*$var}', '<{$var}',
        '/\\{\\*\\$/e', 
        "'{'.\$pagename.'$'");
    }
