I don't know. The list of "other" is pretty big.
It also includes variations of Mozilla, Sahara, and God knows what other open-source stuff that's out there. Wouldn't mind seeing a more detailed list. Hey, how do WE come out on this? Anybody less lazy than me want to look?
BTW, the extra spaces disappearing is very annoying. If I want to do tables, I have to actually replace the spaces with periods, and even then it doesn't line up right.
