This variable just means that "a_b_c" can be completed by
`partial-completion' style to "alonzo_bob_church" and indeed, that
works, AFAICT.

[ completion-styles is used to decide which completion-*-all-completions
  to call, but completion-initials-all-completions should be unaffected by
  completion-styles (and indeed, it isn't, and `partial' is not a valid
  completion style, AFAIK). ]

Indeed, completion-initials-all-completions hard-codes "-" as the
separator (you can see it in completion-initials-expand).
