The indentation works if you want the line to rewrap to the point where 
the line above starts, but in java that's rarely the case.

As someone in the thread said earlier, auto-filling java code is a 
pretty unusual thing to want to do.

Although it is true that auto-fill will break and wrap my line of java, 
and not indent the new line to where it should be, this is in fact a 
minor issue since I mostly want to choose where in the original line the 
line-break should go, manually, but auto-fill automatically takes the 
previous white space.

I realise now that my issue here is that it would actually be preferable 
to have emacs just stop taking input beyond line 72 - and beep instead. 
Or perhaps color the text red, because I can imagine situations where I 
can't break the line.

Is anything like that possible?

Actually is 72 the standard email line length? As I said earlier, my 
requirement is to have all the code easily emailable without being 
rewrapped by the email software.

Cheers
Adam
