A remnant of my MSDOS+C background...

The Python docs say only that the initial letter is checked. And the 
ANSI 89 C says that other characters may follow after r, r+, etc.
"rt" is useless for an ANSI C compiler, since the default stream mode 
is "text" -on systems which differentiate between text and binary- 
and irrelevant on systems which don't do such distinction.
(And since I got used to write "rt", you can infer something about 
*when* I began to write C programs...)
