Readline sometimes doesn't autocomplete until the next disambiguation

[Martin Castillo]

Hi,

consider this folder:

$ mkdir -p "a b/c d e"
$ touch a\ b/c\ d\ e/10._{f,g}

typing
$ ls a\ b/c\ d\ e/<TAB> or
$ ls a\ b/c\ d\ e/1<TAB>
changes the line to
$ ls a\ b/c\ d\ e/10._
as it should, but typing
$ ls a\ b/c\ d\ e/10<TAB>  or
$ ls a\ b/c\ d\ e/10.<TAB>
does not add further characters to the input line.

After
$ mv a\ b ab
typing
$ ls ab/c\ d\ e/10<TAB> yields a partial completion, but
$ ls ab/c\ d\ e/10.<TAB> does not.

The path length seems to influence this bug. But I have no idea how to 
further reduce this problem. Renaming "c d e" to ccdde or cde makes this 
bug disappear.

I am using readline 8.2.001-1.
$ echo $BASH_VERSION
5.1.16(1)-release
