If we can assume POSIX conformance with a reasonable C locale, the
value should be able to contain any non-NUL character. There might be
a line length limit, but that's a different issue.
So I'd rather not document the problem with carriage return as a
feature of Autoconf. It would be OK for now to document it as a bug,
though. Something like this:
In principle the value can contain any [EMAIL PROTECTED] character,
including newline. However, due to deficiencies in common Awk
implementations, it is unwise to put carriage returns or
[EMAIL PROTECTED] characters into the value.
