Tab completion does not work correctly on newly created files.

Version-Release number: bash-2.05b-5

How Reproducible:  Every time.

Steps to Reproduce:

1.  In a shell:

  mkdir tempdir
  cd tempdir
  ls xy<TAB> (and don't press return).

(<TAB> = press the tab key).

2. In a second shell, 'touch tempdir/xyzzy'

3. In the first shell, type <TAB> again.  

Actual Results:

The single possible completion (xyzzy) is displayed on a line, but the command
line being edited does not change:

  ~/tempdir$ ls xy
  xyzzy
  ~/tempdir$ ls xy

Expected Results:

The string "xy" should be completed to the single possibility:

  ~/tempdir$ ls xyzzy
