This is interesting. These two options are mutually exclusive, and
completion-prefix-display-length takes precedence (because they have to
calculate where to start printing the filename differently). The function
that prints the filename has to enforce this, since the function that
calls it does.

This is more cosmetic than anything, since multiple slashes are the same
as a single slash. Plus it's a bash feature; readline doesn't know
anything about globbing.

I suppose bash could tell readline not to append a slash if the pattern
ends with a slash.

This is intentional. It's a way to indicate that the filename begins with
a period. I'll add something to the documentation.
