The patch below would get rid of the error message (and completion, for
that matter) when _init_completion is not present.

I'm not sure whether this is the way to go, or should we rather check
for a recent enough bash-completion during configure, or
recommend/suggest it, or what. The error message does tell us what's
wrong, although it's annoying for the user (probably more so than just
not completing).

BR,
Jani.
