Problem with windows-style line endings.

What steps will reproduce the problem?
1. Build yaml-cpp r98 under Visual Studio.
2. Load a file with windows line endings.
3. Parse the file.  For me, YAML loads a lot of bunk data at the end of the
file that causes errors in ScanScalar.

I was able to fix the problem by changing line 15 of stream.cpp from

pBuf->sgetn(buffer, size);

to:

size = pBuf->sgetn(buffer, size);

I'm not 100% sure I understand the problem, but I think it has to do with
the way the VS CRT handles windows line endings.  I think pubseekoff()
returns the actual character number but sgetn() automatically converts
CRLFs to CRs under the hood, causing sgetn() to read fewer characters than
are in the file.
