Where do these completions come from?

[Dominik Vogt <dominik.vogt@xxxxxx>]

I accidentally hit "d<tab>" and a list of things got displayed
(menu completion), including

  dis_aliases
  dis_builtins
  dis_functions
  dis_functions_source
  dis_galiases
  dis_patchars

"which" doesn't know where these come from; no functions, aliases
or executables.

Questions:

 * Why are these things completed (by expand-or-complete)?
 * How can non-executable strings be excluded from expansion.
 * Where does this stuff come from?  (Only of minor interest)

(zsh-5.7.1).

Ciao
