Elena, 

This is a test that has been failing for me on several native
targets (both i386, though I don't know if that's significant.)

After poring over the results, I've empirically tweaked the 
regular expression until it passes -- but I don't know whether
what I've done is legitimate, or if it merely covers over a
real error, since I don't completely understand what the 
correct behavior is.

Would you mind taking a look at this change and giving it 
a yes or a no?  The big regular expression is the only 
meaningful change.

                                Thanks, 
                                Michael
