Some hooks are generated automatically by AUCTeX parser --- that takes
all the \newcommand and \newenvironment found in the TeX master, and
also loads the styles for \usepackage and \documentclass called from
preamble. Some other hooks are generated programmatically, i.e. for some
package foo.sty you have the equivalent foo.el that is in auctex/styles.

Now if you have some foo.tex in some directory sd/ containing some
\usepackage{foo} you will have an AUCTeX style "foo" that will load two
hooks:
* one from auctex/styles/foo.el, and
* one from sd/auto/foo.el

What I mean by "originator" is something that would allow to
differentiate these two hooks --- no matter how you implement it, the
idea of using a full path needs further discussion --- so that no
stack-overflow recursion is caused (not sure that would happen ?), and
so that sd/auto/foo.el replaces only its hook in the AUCTeX style "foo",
but has not border effect on the hook from auctex/styles/foo.el, and
vice versa.

With originators, I was referring to another potential problem that may
need some provision for making easier solving in the future. See
above...

I think --- but yet I am not fully sure --- that the current solution
which I propose would be sufficient to overcome the foo.tex + foo.bib
situation. What you only need is that BibTeX would set new variable
TeX-style-hook-context to :bibtex, so that LaTeX hooks do not do some
undesirable setting in foo.bib, and vice versa --- well to my knowledge
there are not yet BibTeX or Texinfo auto hooks, but that could happen in
the future --- after all one can define some @macro in Texinfo and
@string in BibTeX.

When some day, someone would put on the table such parsing for
generating auto hooks for Texinfo or BibTeX, one would then certainly
need that LaTeX auto hooks are in a sd/auto_latex, and similarky
sd/auto_texinfo and sd/auto_bibtex for Texinfo auto hooks and BibTeX
auto-hook respectively, this way foo.bib, foo.texi and foo.tex, all
bad-luckilly in the same sd/ directory would not collide their
respective foo.el generated automatically.
