Code etiquette - tabs or spaces?
cperciva: To quote BSD style(9): Indentation is an 8 character tab. 
If you have to wrap a long statement [because it would go past the 78th column], put the operator at the end of the line.  Second level indents are four spaces.  Do not add whitespace at the end of a line, and only use tabs followed by spaces to form the indentation.  Do not use more spaces than a tab will produce and do not use spaces in front of tabs.If you find that your code doesn't fit into 78 columns using 8-character tabs... you need to refactor your code.If your editor mangles whitespace... get a better editor.
