prompt overwritten after tab completion - possibly fixed in readline 5.2

[Mikel Ward]

Hi

On my newer systems (e.g. Red Hat Enterprise Linux 5.2), I had noticed
a problem with tab completion.

I can't reproduce it on my system which has readline-5.2-13 (versus
readline-5.1-1.1), so I'm guessing it's fixed in readline-5.2, but the
CHANGES list doesn't explicitly mention anything like this, so I
thought I'd mention it anyway.

> cd tmp/<TAB>
foo.1/ foo.2/
> cd tmp/foo.

The cursor is placed immediately after the prompt (>), rather than at
the end of the completion (.).

Disabling either horizontal-scroll-mode or
print-completions-horizontally in ~/.inputrc makes it work OK.  I
chose to disable horizontal-scroll-mode.
