The cause is the defined `advertised-calling-convention' for
`display-completion-list'.  Declaring an `advertised-calling-convention'
is the standard way to tell people that the signature of a function will
be changed in the future.  It has been discussed some while ago whether
this way to provide this kind of information is appropriate.

Anyway, as long as the old signature is supported, the recursive call
will probably have to break the new calling convention.
