Btw the reason for the /dde parameter is simply so that if the user runs
winebrowser from the command line he/she does not have to wait for the 5
second timeout before they get a usage message.

On windows there is no such parameter passed to iexplore (although
-nohome is passed so it doesn't open a homepage) as iexplore will
actually open a window that will then sit and wait for the DDE server
request. Since winebrowser does no such thing, and will exit once it
starts the appropriate unix browser, we have to have a timeout, but if
we pass a special command line parameter we will know only to wait for a
dde request if it is passed, so a commandline user can see his usage
message right away.
