Summary: mailbox._Subfile readline() bug

Initial Comment:
mailbox._Subfile's readline() will chop off the first
character of the next line when reading Unix-style
terminated files.  It's surprising no one has mentioned
this before.

The problem lies in line mailbox._Subfile.readline()
itself where self.pos is assigned self.fp.tell()'s
value.  You will need to subtract 1 from self.pos if a
file uses unix-style termination.

There doesn't seem to be a clean way to fix the code.  But
there is a rather satisfactory workaround:  Open the mbox
file in binary mode for Unix (and Mac?) style terminated
files.  This should DEFINITELY be mentioned in the mailbox
module docs.
