Yep, that's what it was supposed to do.

Sometimes it's pretty handy. I don't mean formatting comment contents, but try 
this:

struct {
	int a;		// blah
	int b;		// blah blah
}

That's what it's for. I'm sure some will do it like this:

struct {
	// blah
	int a;
	// blah blah
	int b;
}

but for some large structs it's not nice (makes the struct take twice the 
lines, so at least on 80x25 consoles it's not very coder-friendly ;-).

Thanks :), somebody pointed me to webcvs in the meantime (gosh, how could I 
have forgotten about webcvs???)

I'll be doing this in a couple of weeks.

What's nedit (didn't have time to search, sorry). I would be interested if 
nedit is cool and if it's worth it.
