| Analysis:
| 1. At first, tex-site.el declares the following defalias and autoload:
| (defalias 'texinfo-mode 'TeX-texinfo-mode)
| (autoload 'TeX-texinfo-mode "tex-info")
| 2. So typing M-x texinfo-mode leads to loading tex-info.el, which
|    contains a form
| (require 'texinfo)
| 3. Then texinfo.el, bundled with emacs, is loaded, resulting in that the
|    above defalias for texinfo-mode is overwritten by
| (define-derived-mode texinfo-mode text-mode "Texinfo"
|    in texinfo.el.
| 4. Therefore, the overwritten function definition is used for M-x
|    texinfo-mode, ignoring the TeX-texinfo-mode defined in tex-info.el.
