send-mail-function: different default on Win/OSX

[David Reitter]

With the current defaults, Emacs is unable to successfully send off a  
bug report (or any other mail) out-of-the box on Mac OS X, and I  
suspect it won't work on Windows either. The reason is the default  
for send-mail-function, which is changed on these systems with the  
following patch.

(Richard, I sent you an earlier version on August 14, which hasn't  
been checked in.)
