I would already be happy with a portable function that allows to
switch stdin or stdout to binary mode and that has only a well-defined
behaviour according to the standard if this switch occurs before any
byte has been written to or read from the stream. This would cause no
headaches on your computing fossil (because inserting a newline during
a later switch would not be non-conforming) and would be sufficient
for all important applications I can think of (like zcat).
