bug#69187: 29.2; Poor compatibility in align.el

[Ikumi Keita <ikumi@ikumi.que.jp>]

[Summary]
There is an entry in `align-rules-list' incompatible with recent AUCTeX
change (and possible user-defined derived mode).

[Detail]
In `tex-tabbing-separator' entry of `align-rules-list', the run-if
property contains a conditional (eq major-mode 'latex-mode). This isn't
compatible with AUCTeX 14, which changes its major mode name from
`latex-mode' to `LaTeX-mode'.

Apart from AUCTeX issue, this entry doesn't work in user-defined derived
mode such as
(define-derived-mode latex-thesis-mode latex-mode "LaTeX-Thesis")
as well.

I propose to change this entry as:
    (tex-tabbing-separator
     (regexp   . ,(lambda (end reverse)
                    (align-match-tex-pattern "\\\\[=>]" end reverse)))
     (group    . (1 2))
     (modes    . '(latex-mode))
     (repeat   . t))

This entry becomes effective in doctex-mode also because it is derived
from latex-mode, but I don't think it matters.

Regards,
Ikumi Keita
