Info mode misformats menu entries with refs in description

[Tim Van Holder]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
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 address@hidden mailing list.

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


The bison manual for version 1.875 contains a menu entry (Pure Calling)
that has a @pxref in its description.  While standalone info handles
this just fine, it seems to cause the emacs Info reader to justify
the menu block as a paragraph, losing menu functionality.

Note that standalone info does have a quirk related to such refs - when
they are selected, info will jump to the menu entry's node, not the node
specified in the ref.

The problem can be reproduced by this simple TeXinfo file:

>>> start of snippet
\input texinfo @c -*-texinfo-*-
@setfilename foo.info
@settitle Hello World

@finalout

@node Top
@top

@menu
* hello::             blah blah (@pxref{world, ,foo}).
* world::             more blah-di-blah.
@end menu

@node hello
@unnumbered Hello

Hello

@node world
@unnumbered World

World

@bye
>>> end of snippet
