Commit: Ikumi Keita <ikumi@ikumi.que.jp>

    Remove compatibility code for Emacs<24.3
    
    * latex.el (LaTeX-insert-left-brace):
    * tex.el (TeX-insert-dollar):
    Simplify the property `delete-selection-mode'.
    (VirTeX-common-initialization): Use " " for `comment-padding'.
    (TeX-math-input-method-off): Never use `inactivate-input-method'.
