I'm not wild about these big boolean statements, but I also don't see something
that is obviously better. Typically we want to see indentation with tabs and
alignment with the initial line's arguments with spaces... but here that just
looks ugly as the too seemingly similar blocks end up with different
indentations due to the if and return... anyway, subjective and all that. So I'm
leaving it mostly alone, but I dropped one set of tabs from the above lines and
queued it.
Thanks Adam.
