Idiomatic portable way to strip line endings? (fwd)

[Russ Cox]

As has already been pointed out, section 7.19.2 of
the ANSI C99 standard mandates that stdio FILEs
opened in text mode are sequences of lines, each
of which is terminated with a newline character.
I believe this was the case for the C89 standard too.

If you open in binary mode then you have to deal
with the differing line-ending conventions on 
various systems.  If you open in text mode, you
should always get a single \n (\012); nothing more,
nothing less.
