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.
