Trivial fix to annota1.exp

[Jim Ingham <jingham@apple.com>]

I think that the backtrace through a signal handler test in annota1.exp 
is wrong.  It uses a "*" in the regexp for the part that is looking for 
the signal handler frame.  Because of that, all the test really does is 
count the number of frames, and require they be three or more frames.  
It doesn't check that a signal frame is on the stack at all.

I think you really need a "+" instead, or I don't understand the point 
of the test.

Is this okay, it still passes on Linux...
