(Fore some value of "soon", sorry.)

I fixed this bug.

There were two suggestions for how to fix this: one by Handa-san in
this message:

  http://lists.gnu.org/archive/html/emacs-devel/2008-08/msg00293.html

followed by a tentative patch by Juanma here:

  http://lists.gnu.org/archive/html/emacs-devel/2008-08/msg00316.html

The other suggestion was by Stefan:

  http://lists.gnu.org/archive/html/emacs-devel/2008-08/msg00373.html

I decided I liked the first alternative better, since it has much
more local effect than the other one.  What Stefan suggested implied
messing with coding priorities, and I didn't feel that was TRT at this
late stage in Emacs 23.1 development.

The changes I installed are more thorough than what Juanma posted:
they change both detect_coding and detect_coding_system, and also bind
inhibit-null-byte-detection in a couple more places in info.el.

The result was tested on GNU/Linux, MS-Windows, and MS-DOS, both with
compressed and uncompressed Info files, with auto-compression-mode
both on and off.
