bug#19697: 25.0.50; Emacs manual line is 239 chars wide!

[Drew Adams]

Line 31 of node `Language Environments (and another line is almost as
long):

     Chinese-GBK, Croatian, Cyrillic-ALT, Cyrillic-ISO, Cyrillic-KOI8, Czech, Devanagari, Dutch, English, Esperanto, Ethiopic, French, Georgian, German, Greek, Gujarati, Hebrew, IPA, Italian, Japanese, Kannada, Khmer, Korean, Lao, Latin-1,


That line will get wrapped by the mailer, but you can check it yourself easily.

I do not observe this problem on Fedora 21 x86-64.  Lines 31-34 are:

      Cyrillic-ALT, Cyrillic-ISO, Cyrillic-KOI8, Czech, Devanagari,
      Dutch, English, Esperanto, Ethiopic, French, Georgian, German,
      Greek, Gujarati, Hebrew, IPA, Italian, Japanese, Kannada, Khmer,
      Korean, Lao, Latin-1, Latin-2, Latin-3, Latin-4, Latin-5, Latin-6,

which look fine.

It could be a 'makeinfo' or platform issue.  I'm using makeinfo (GNU texinfo) 
5.2, as shipped with Fedora.  Here's how the .info file was built:

$ cd doc/emacs
$ rm ../../info/emacs.info
$ make V=1 ../../info/emacs.info
makeinfo --force --enable-encoding -I . --no-split -o ../../info/emacs.info 
emacs.texi

Your reply indicates that this might be a build or platform-dependent
bug, which is useful info.

It might also be a problem that has already been fixed.  The build
I reported about is from October 2014.

This is indeed a bug in makeinfo 4.x which doesn't exist in 5.x.

IOW, not an Emacs problem.

No, it wasn't; there's nothing to fix.  The Texinfo sources are OK as
they are.

I see.  I thought that Emacs was responsible for, or able to take
care of, line lengths.  Anyway, OK by me if you close this as not
an Emacs bug.

The line length in the Texinfo sources is just fine.  It's just that
makeinfo renders this particular place incorrectly.

If there's a rainy day soon, I might try something to work around the
makeinfo bug.

I thought that @refill would help, but it didn't, unfortunately.

Thanks, done.  Eventually everybody will be using newer Texinfo so the 
bug will fix itself in time anyway....

I found a way to kludge around the bug in Texinfo, and committed the
result to the emacs-24 branch.

Excellent.  Thx.
