bug#18308: 24.4.50; Info viewer cannot follow menu entry for '(texinfo) @- @hyphenation'

[Vincent Belaïche]

Dear Eli et alii,

Looping also through Gavin.

For your information I have filed these two bugs to texinfo.

http://savannah.gnu.org/bugs/index.php?43045
http://savannah.gnu.org/bugs/index.php?43042

During the discussion on bug-texinfo@gnu.org concerning texinfo
bug#43042, I received the following comment from Gavin Smith:

I a nutshell, there are cases of node references where the info viewer
is not bothered by internal multiple spaces (this cross reference inside
bash manual), and other cases where the info viewer cannot handle it
(the case of node "(texinfo) @- @hyphenation" pointer in menu entry of
upper node).

So, on second thoughts, I am thinking in the end that for consistency,
the info viewer not only should, but also _must_ be corrected.

I am even speculating that in the case of the manual menu entry,
probably it was intentional to put more spaces for the entry to read
better (as @- and @hyphenation are two different commands, isn't it a
good idea to put a little more space between them).

Maybe the texinfo manual could also be corected as follows (with two
spaces in label, and one space in node pointer):

* @t{@@-  @@hyphenation}: @t{@@- @@hyphenation}.            Helping @TeX{} with 
hyphenation points.

ie by using the

* LABEL: NODE. TITLE

construct instead of the

* NODE:: TITLE

construct. Well... this is not your business, but if Gabin had read this
email up to this point, he may have an opinion.

VBR,
   Vincent.
