[elpa] externals/auctex ddb0f08ff1 10/24: Add default entries to LaTeX-indent-environment-list (bug#28405)

[Tassilo Horn]

branch: externals/auctex
commit ddb0f08ff1adb8a89f2d808dd6109ed535e552b3
Author: Ikumi Keita <ikumi@ikumi.que.jp>
Commit: Ikumi Keita <ikumi@ikumi.que.jp>

    Add default entries to LaTeX-indent-environment-list (bug#28405)
    
    My previous commits disregard user's customization on
    LaTeX-indent-environment-list. Reconsideration led to move entries to
    its default value.
    
    * style/amsmath.el ("amsmath"):
    * style/mathtools.el ("mathtools"):
    Move entries into default value in latex.el.
    * latex.el (LaTeX-indent-environment-list): Pull in those entries.
    Add math envs without alignment as well to fix bug#28405.
