Bug#1986: stdio broken? Strange behaviour of fgets() and scanf()

Yes, it still fails. I tried removing the #define from the start of the
string to be matched, though, and it no longer fails. OTOH, the original
program (which is too long to reproduce here) which reads a file largely
consisting of #define SYMBOL VALUE lines also fails, reading to the end
of the file and then carrying on reading nothing.
