There's still something wrong to me in the solution provided by Tassilo.
It works fine, but it is returning a function to bypass the usual
completion code completion code. Ignoring case, like doing smarter
completion (e.g. where the typed prefix does not match the returned
choices at all) is something that is very useful.

Therefore I wonder if we should either:
- Edit `completion-at-point-functions' docstring to remove the word
  "discouraged" in that sentence:
  "or a function of no argument to perform completion (discouraged),";
- Make completing code allows to replace the region being completed with
  somethig that does not match at all.
