It introduces another annoying bug: hitting TAB when the list of
possible completions is empty signals an error.  For example, if you
do (completing-read "Foo: " nil) and hit TAB, you get:

Debugger entered--Lisp error: (args-out-of-range "" 0 1)
  PC-do-completion(nil)
  PC-complete()
  call-interactively(PC-complete)
  completing-read("Foo: " nil)
  eval((completing-read "Foo: " nil))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp)
