[Xastir] Transmit Shapefile ?

On Tue, May 20, 2008 at 02:37:48PM -0400, we recorded a bogon-computron collision of the <mckeehan at mckeehan.homeip.net> flavor, containing:

Unfortunately, the multline protocol might not help you there, either --- I 
have no idea how widely implemented it is in other clients, and as you point 
out, the wxsvr.net web site where the protocol is documented (and which
lists the clients that support it) seems to be down.

I'm sorry I haven't had time to look at the code snippet you sent me, it's
a busy week of work and family stuff.  I'll try to see if it's a problem in 
what you're passing the code or with the makeMultiline code itself.  All of my 
prior testing has been with those ellipses in the test code I sent you, 
because that was all I needed.  An error involving the orientation that you're 
seeing wouldn't have been exposed in my testing, so I can't guarantee that 
makeMultiline is bug-free.
