Ouch.  That's certainly way too much.  Is the compiler inlining
process_log_prefix_padding()?  If not, does it do it if you add "inline"
to it?  That might speed up things a bit.  If that's not enough, maybe
you need some way to return to the original coding for the case where no
padding is set in front of each option.
