Thanks for the report.  It wasn't a dumb question at all.  I don't think
that you are the first to report this, but it finally sunk into my
feeble brain that there may be a problem here.

I took some time to investigate this, and there is actually a problem in
the rewritten \r\n text handling code in cygwin.  It looks like the
problem has existed since 1.1.1.  The symptom is that when cygwin wrote
out a buffer, it would add a \r in front of any \n regardless of whether
the '\n' was already preceded by a \r or not.

I've fixed this, so it will be in the next snapshot.  Please give it a try.
I'd like to nail this down for 1.1.5.

Thanks for the bug report with a simple example that I could easily
duplicate.
