I suspect it's a resource compiler thing. The history predates the 
mailing-list archives at winehq and also my own mail archive so it must be 
before 1999, but IIRC at that time the only resource compiler to support 
multi-line text was Borland's. At the time I was tinkering with WineLib 
applications and also working on wcmd, so I suggested to the developer of 
Wine's resource compiler that he follow the Borland convention. It seems 
that MS compilers now accept a similar but incompatible syntax (how unusual) 
which is the cause of your confusion.
