A bug in the Windows C Runtime causes text mode pipes to drop newlines
sometimes. This bug was hidden because of another bug in rcc which
caused newlines to be redundantly duplicated. When the latter bug was
fixed (commit 53d5811b) the former bug was exposed, causing invalid
vcxproj files to be generated. The Windows bug is described here:

The workaround is to avoid text mode, and do the conversion of "\r\n"
to "\n" ourselves (which we were already doing anyway).
