+
+-----
+If you're going to be patching htmllink anyway, might I suggest something more flexible, like being able to configure the link format?
+(Yes, PmWiki allows this, that's where I got the idea)
+That is, rather than having "<a href=". blah . blah ...
+one could use a sprintf with a default format which could be configured in the setup file.
+
+For example:
+
+ $format = ($config{createlink_format}
+ ? $config{createlink_format}
+ : '<span class=\"createlink\"><a href="%s" rel="nofollow">?</a>%s</span>');
+ return sprintf($format,
+ cgiurl(do => "create", page => lc($link), from => $lpage),
+ $linktext);
+
+I admit, I've been wanting something like this for a long time, because I dislike the existing createlink format...
