dumb (easy-to-fix) mistake in sage notebook js.py file

[was]

Reported by Ralf Hemmecke:

Oh, it's a bug. It hit me again... :-(

sagenb-0.8.p2/src/sagenb/sagenb/notebook/js.py

says

try:
   from sage.misc.misc import SAGE_ROOT
   from pkg_resources import Requirement, working_set
   sagenb_path = working_set.find(Requirement.parse('sagenb')).location
   debug_mode = SAGE_ROOT not in os.path.realpath(sagenb_path)
except AttributeError, ImportError:
   debug_mode = False

But according to what I cite below, it should rather be

except (AttributeError, ImportError):

http://docs.python.org/tutorial/errors.html

A try statement may have more than one except clause, to specify
handlers for different exceptions. At most one handler will be executed.
Handlers only handle exceptions that occur in the corresponding try
clause, not in other handlers of the same try statement. An except
clause may name multiple exceptions as a parenthesized tuple, for example:

... except (RuntimeError, TypeError, NameError):
...     pass

What happens if the bug was fixed before the track ticket was reported? :)
