Bug & patch : balsa-message.c

[Emmanuel <e allaud wanadoo fr>]

  Hi all,
this patch corrects find_beg_and_end in the corner case when str+pos
points on a \n.
Indeed the function returned the correct beginning (the first char after
the first \n preceding the one pointed on by str+pos) but the resulting
end was pointing on the last char before the first \n (or \0) following
the \n pointed on by str+pos so that there were 2 paragraphs between the
begin and end returned by the function.
Last but not least the function is now a lot simpler.
