i knew this patch would get comments, it was just a question of when.

so far, i can't think of a reason not to do as you suggest.
i'll think about it some more and maybe take your advice.

you mean, you want to see
  if (condition)

instead of
  if (condition)


... right? is there a consensus on this, or is it part of our coding
standard? personally i sometimes like a blank line before an else
statement, but i don't feel strongly about it.

i think i like it.

i don't understand what you're saying here.

ooh, that i will definitely fix.

thanks for the eyes, late is better than never. :)
