* Okay, I think there could be a much more elegant way of doing
* this... but I'm having a hell fo a time figuring it out.
*
* The purpose of this function is to take a menu path and turn it
* into a caption that we can put in a tab. Why do it this way? I
* don't know, you tell me. Before I started hacking this we used a
* radio control with two buttons (or so it seemed, I could be wrong)
* with General and Advanced in a ui.rc file.
*
* Now that we're using tabs, we no longer have that UI file giving us
* the names for the tabs, and since I didn't want to hard-code
* anything, and since KSycocaEntry stuff doesn't give you a nice way
* (that I noticed anyway) to figure out what your caption should be,
* I decided that cleverness is lost on this problem. So screw it,
* I'll just parse the stupid path and be done with it.
*
* This function is certainly nothing short of dull and boring and
* routine, but I figured that this might require a bit of explanation
* since it just seems kinda silly to do it this way to me. I guess I
* never know... I could be doing it the best way.
