Description of problem:
When there is a read statement expecting a single entry and a single
comma is entered, the read expects more input.

The test program is:

      stuff = 1
      stuff2 = 2
      write(*,'(1x,a,$)')'Enter 2 somethings: '
      read(5,*)stuff,stuff2
      write(*,'(1x,a,$)')'Enter something: '
      read(5,*)stuff
      call exit(0)
      end

[ashtray] image 205 % gfortran -o inputbug inputbug.f
[ashtray] image 206 % ./inputbug
 Enter 2 somethings: ,,
 Enter something: ,
,
/

[ashtray] image 207 %

It does not accept a , as a default entry for a single number, although two 
commas work when two numbers are expected.  Once it gets on comma it even refuses a / until a second return is entered.




Version-Release number of selected component (if applicable):
gcc-gfortran-4.0.2-8.fc4

How reproducible:
Always

Steps to Reproduce:
1. compile program 
2. run program, enter ,, then ,
3.
  

Actual Results:  Failure to accept , on second input

Expected Results:  [ashtray] image 208 % g77 -o inputbug inputbug.f
[ashtray] image 209 % ./inputbug
 Enter 2 somethings: ,,
 Enter something: ,
[ashtray] image 210 %
