Description of problem:
If you attempt to use tab completion in a command substition between quotes, a space is put after directory names instead of the slash.

Version-Release number of selected component (if applicable):
bash-3.0-18

How reproducible:
Always

Steps to Reproduce:
1. type: echo "$(cat /h
2. press tab to complete /home
  

Actual Results:  Shell expands the command to `echo "$(cat /home '

Expected Results:  Shell expands the command to `echo "$(cat /home/'

Additional info:

Expansion works correctly if you use either quotes or command substitiution, it even works if quotes are used inside the command substitution. Command substitution should work the same no matter which context it is used in. It is puzzling me how it is even possible to introduce a bug with exactly these symptoms, it may be a symptom of some more fundamental flaw. I'd like to keep this bug private until we know if it have any security implications.
