+ What we have is an internal buffer, which is 8 characters
+ longer than the actually used buffer. E.g. say BUFSIZ is
+ 512 bytes, then we actually allocate 520 bytes. The first
+ 2 characters will be junk, the next 2 characters set to NUL,
+ for protection against some backward-compares. The fourth-last
+ character is set to '\n', to protect against overscan. The
+ last 3 characters will be junk, to protect against memory
+ violation. intBuffer is the internal buffer, but everyone refers
+ to fbuf, which is actually set to the &intBuffer[4]. Also,
+ szfbuf is the size of the "visible" buffer, not the internal
+ buffer. The reason for the 2 junk characters at the beginning
+ is to align the buffer on a 4-byte boundary.
