Summary: PyMarshal_ReadFileFromLong()

Initial Comment:
Here is some documentation for marshal.

long PyMarshal_ReadLongFromFile(FILE *fp)
Read four bytes from an open file pointer, and return a 
long.  The
file bytes are in little-endian order; the least 
significant byte
is first.  The long is considered to be signed.  That 
is, if
the 4-byte long is negative, and if the size of a 
native long
is more than four bytes, the long is sign extended.

int PyMarshal_ReadShortFromFile(FILE *fp)
The same as PyMarshal_ReadLongFromFile(), but read two 
bytes,
sign extend, and return an int.

The error reporting behavior of these functions is
questionable at best; perhaps something that can clearly
distinguish between errors and negative numbers makes more
sense?

Anyway, I've checked in docs for what is currently there as
Doc/api/utilities.tex revision 1.2.
