This is what I cannot reproduce. The expansion is correct. If I run
`echo echo' and then type ^Re, whether horizontal scroll mode is enabled
or not, I get the cursor positioned before the `e' in the second echo,
and readline rings the bell to indicate there are no (or more than one)
completions. If I hit return, I see `echo' displayed.
The `echo readlineline' from the previous example is another example of
the same correct behavior.
I'm using bash-4.3.30. There was a previous patch (bash-4.3.13/
readline-6.3.6) that affected horizontal scrolling, but I don't know
what version you're using. Distribution version numbers are not
necessarily related to the upstream patch level.
