Backport PR : Avoid stopping in ipdb until we reach the main script....

Backport PR : Avoid stopping in ipdb until we reach the main script. For example: ``` In [1]: %run -d -b 52 setup.py Breakpoint 1 at /tmp/ipython/setup.py:52 NOTE: Enter 'c' at the ipdb> prompt to start your script. > /tmp/ipython/setup.py(7)<module>() 6 Under Windows, the command sdist is not supported, since IPython ----> 7 requires utilities which are not available under Windows.""" 8 ``` compared to the previous behavior: ``` In [1]: %run -d -b 52 setup.py Breakpoint 1 at /tmp/ipython/setup.py:52 NOTE: Enter 'c' at the ipdb> prompt to start your script. > <string>(1)<module>() ``` Closes ("List command desn't work in ipdb debugger the first time")
