bug#12948: 24.1; wrong angle brackets

[Mattias Engdegård]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

With the TeX input method, \langle and \rangle yield the deprecated
characters U+2329 and U+232A rather than the ones at U+27E8 and U+27E9
which are for mathematical use and Western languages. The former
characters should not be used; they are troublesome because of their
canonical equivalence to CJK punctuation, and are frequently rendered
(correctly) as having the full width of a CJK character.

These definitions are in leim/quail/latin-ltx.el. The same file also
produces the deprecated angle brackets from \leftparengtr and
\rightparengtr, but this makes even less sense, since those names should
properly be used for U+2993 and U+2994, unless I'm completely mistaken.

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'.
For information about debugging Emacs, please read the file
/usr/local/emacs/24.1/share/emacs/24.1/etc/DEBUG.
