- 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.
