If in doubt, look at a standard. Here's what draft 7 of new POSIX says:

"First (if s is not a null pointer and the character pointed to by s is not
the null byte), the string pointed to by s followed by a colon and a <space>.

Then an error message string followed by a <newline>."

I don't have time to look at C99 right now. But POSIX embraces that, so it
should be the same.
