+    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.
