It is very inconvenient to debug higher-order functions when part
of functionality is implemented in C.  This is another reason to
move completion functions to Lisp.

Nevertheless, I've found that this was caused by internal-complete-buffer
that really uses a cons pair of (buffer-name . buffer) for the
buffer name argument.  I installed a fixed version of
