Heh, I pay too much attention to how the code looks like...  I have
very strict rules about it, and I almost never let myself go around
them, even when I debug it.  (This results in some incompatibilities
with the currently blessed style -- for example, I keep code at a
width of <=79 chars (or in rare cases at 80); but OTOH I stick in most
cases to putting as much on one line as possible within this limit.)
