Remove CRLF

[Michael Young]

Jon, Robert offline (I think), Xavier, Mark Smith and others helped me 
figure out the issue. Thanks to everyone for their input.

I could truly see that %Od, otherwise known as <CR>, was the offending 
code left behind when I tried to strip off the CRLF after adding the 
CRLF myself. I had one prototype stack with one card on OS X in which I 
entered the data and processed the data. So, the issue is 
cross-platform but I myself stayed on one platform, one mainstack, and 
one card.

The problem should have been a lot simpler to solve. For example in 
National Instrument's ( http://www.ni.com/ ) LabVIEW 10 years ago when 
I used their line ending codes rather than ASCII codes 10 and 13, etc. 
the line ending issue was handled behind the scenes and just worked. I 
also did not have CPU endian issues in LabVIEW because data was put to 
disk and internally handled in Motorola endian format even if LabVIEW 
was running in Windows on Intel hardware. LabVIEW did the heavy lifting 
for me.

I learned that just using LF rather than CRLF gave me the cosmetic 
effect that I wanted and the LF stripped off automagically as people 
are want to say.

I do not understand why such a simple problem had to be so tricky in RR.

I have filed a bug report.

PS This simple problem was part of my attempt (that ultimately 
succeeded, yeah) to recreate the demo REALbasic 2005 tutorial example 
that of course truly just worked simply. Sigh.
