Fix an assertion failure raised by the following interesting scenario: a

auto-opened `It' (i.e., a column list with a free-text first line) with
leading spaces in the line triggering assertion when searching for
arguments.

This led to a fix giving a nice performance speed-ups (a few percent,
with some quick trials): the search for flags immediately exits if the
macro has no flags, instead of having to first parse the leading word
then look it up.  I also cleaned up the argv parsing stuff a little bit
and added more documentation.

This comes from a TODO by joerg@.
