Bash Version: 4.1
Patch Level: 5
Release Status: release

Description:

If a directory is a subdirectory of / and has four or five characters in
its name, the PS1 prompt is wrong for it.  Examples below.


Repeat-By:

# Run the commands below.

address@hidden:~# export PS1='\h:\W '
a01:~ cd /abcd
a01:acdd

a01:~ mkdir /abcde
a01:~ cd /abcde
a01:abdde cd ..

You can see that the prompts are garbled.

Fix:
        I don't have a fix.
