Yes, that makes sense.  Indeed, there's a problem in the completion
system: we don't distinguish between a valid input and a completion
candidate.  "ess-5.3.10/" is a valid completion candidate, but is not
a valid input.

IIRC there are cases where the completion primitives make it difficult
to enforce this distinction (e.g. when we provide a predicate, where it
can be OK to ignore the predicate on intermediate completions like
"ess-5.3.10/"), but in the case of load-library's completion, it should
be fixable without too much trouble.
