I've said this stuff before:

I indent things using two spaces.  I mostly adhere to Sun's style 
guidelines.  However, there's a tension there between the 
four-spaces-per-indent-level rule and the 80-columns rule.  Unlike most 
Java programmers, I choose to obey the 80-column rule.  I edit in an 
80-column wide Emacs window, and don't like wrapped lines.  Indenting 2 
spaces makes this workable.  I also just like the way 2-space indenting 
looks.  Call me crazy and anti-social.

We should be tolerant of other coding styles.  Lots of folks put opening 
brackets on separate lines, prefix field names with underscores or 'm', 
have 120 column lines, and other things that I would never do.  I think 
it is rude to re-indent or otherwise re-style a whole file, unless it is 
unlikely that the original author will ever edit it again.  I think it 
is polite, if you make a one or two line change, to make it in the 
file's existing style.  For larger changes, say ten lines or so, I think 
it is fine to use a different style than that used in the rest of the 
file.  If you do a major re-write, then re-indenting is fine.  Styles, 
like accents in spoken language, give code character.  There is no 
univerally acceptable style.  Unless something is unintelligable, we 
needn't re-state it.
