It seems to me that Emacs users often use "my-" prefix or person's
initials (like "tl-" or "tl/") as prefix when writing their private
extensions and configuration. However, there is no officially documented
prefix which Emacs promises to leave for users. So I suggest making such
promise and documenting it in info page "(elisp) Coding Conventions"
(example patch below).

What is suitable prefix? It should be short. "my-" and "user-" are
already used somewhere.

 If one prefix is insufficient, your package can use two or three
 alternative common prefixes, so long as they make sense.
