fopen rb

[Paul Kienzle]

It seems the default open mode for files in matlab on
Windows changed from text mode in 1994 to binary
mode today.  We are defaulting to text mode.  Also,
we do not mention 'b' and 't' flags in the help text.

The attached (untested) patch changes the default
open mode and updates the documentation.  Hopefully
this won't be a problem for any of the 14000+ users who
have downloaded the windows binary when we change it.

I'm not thrilled to have a different default from the POSIX
interface --- it will surprise C programmers.  Having a
different default from Matlab will surprise a different set
of users.  Maybe we could warn if neither 't' nor 'b' are
specified?  I'm not too thrilled about that either.
