title: python pdb unt at end of loop
body: <p>I have been using pdb's "unt" command to step over list comprehensions with a single command. This works well unless the list comprehension happens to be at the end of the loop. Then the "unt" command steps over the entire loop.</p>
  
  <p>It seems to me that this is a flaw in the definition of the "unt" command. Is there a reason why it wasn't defined as continuing execution until the current line changes, rather than waiting for it to increase?</p>
