Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I am running shell (bash). When I do cd and press tab to cause completion, I 
see 
multiple ./././././ if the directory is empty or the whole content of the 
directory 
even though the TAB was pressed when only a part of the target directory was 
input.
I also noticed that in the latter case the content of just one directory was 
displayed 
even though more than one match existed.
