Recommended way to add allowed style classes?
I noticed that since updating to 2.2, the GeSHI syntax highlighter plugin I'm using has broken. Some poking around reveals that the HtmLawed plugin is stripping out all of the class attributes, so I'm just left with a bunch of blank span tags.
To fix it I had to edit class.htmlawed.plugin.php and add a number of allowed classes (geshi_syntax, code, br0, co2, kw2, kw4, kw5, nu0, objc, sy0, probably more, but these are what I found in one render).
Is there a recommended way of doing this, from within the GeSHI plugin itself, that doesn't require this hack approach?
Is there a better way to approach this problem?
