A thing I just found out today: Windows clients expect
messages to begin with \pard (not \par) and expect
paragraphs, including the last one, to end with \par.
Otherwise, Windows users see an unneeded clean
paragraph between ICQ's status line (with your name)
and your text, and _no linebreak at all_ between your
last line and ICQ's own status line.
This patch fixes it by inserting \pard anyway and adding
\par AFTER the paragraph.
