bug#876: ^M in some Windows info files because of null-byte detection

bug#876: ^M in some Windows info files because of null-byte detection

[Juanma Barranquero]

Some info files in Windows (for example, the Emacs FAQ) are displayed
with spurious ^M characters because of recent changes in null byte
detection.

Kenichi Handa proposed a new inhibit-null-byte-detection variable.
Stefan Monnier counter-proposed inhibit-coding-systems.

I thought #876 was resolved long ago.  Why wasn't it?

  Stefan Monnier counter-proposed inhibit-coding-systems.

Also, the manual name should be listed in `dir' as `Viper', not `VIPER'.

We just honor the manual's request here, which specifies this DIR
entry in viper.texi:

    @direntry
    * VIPER: (viper).       The newest Emacs VI-emulation mode.
			      (also, A VI Plan for Emacs Rescue
			       or the VI PERil.)
    @end direntry

So it sounds like VIPER is actually an acronym, or at least it used to
be.

bug#1816: 23.0.60; ^M in CC mode manual.

[Matzi Kratzi]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

All (probably most) lines in the CC Mode info manual are ended with ^M.
I use a build from Lennart Borgman.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/Download/emacs-090104/emacs/etc/DEBUG for instructions.

(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.

(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.

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

All (probably most) lines in the CC Mode info manual are ended with ^M.
I use a build from Lennart Borgman.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file

RE: ^M in the info files

[Drew Adams]

Thanks for fixing this. 

bug#1845: Acknowledgement (^M in the info files)

[Drew Adams]

Something wrong here, it seems.

I received this ack, and another one (identical) for new bug #1844. I filed no
such new bugs. I simply replied (once) to Eli's message saying that he had fixed
bug #876, by saying thank you.

The bug tracker seems to be inebriated again.

Also, I've recently received acks apparently intended for others, with no
connection to any bug ever filed by me or any mail ever sent by me. I assume
that others have also received such spurious acks.

[ Obviously my suggestion requires more work to implement, but.. ]
Hmm...curious, why does it involve coding priorities?

You suggested to introduce a way of controlling which possible
encodings will _not_ be acceptable by the caller of
detect-coding-region/string.  These primitives work by scanning the
coding_priorities[] array and checking them against those categories
that has been rejected based on the text in the region/string.  See
detect_coding and detect_coding_system.

Please stop cc'ing emacs-pretest-bug@gnu.org and bug-gnu-emacs@gnu.org
in this discussion, it messes up the bug tracker.

Why won't the tracker get its act together and stop forcing us into
editing mail headers?  I use the Rmail's `r' command, which replies to
all the original "To" and "CC" addressees.  With the amounts of mail
I'm responding to, I cannot afford editing headers of every message I
send.  Even if I try, I will surely sometimes forget.
