[Configobj-develop] [PATCH] Don't use hasattr

[Matt N. <mno...@ma...>]

Hi.

Python's hasattr() function swallows all exceptions, including things
like KeyboardInterrupt. Therefore, one project I tinker on (Bazaar) uses
"getattr(object, 'attribute', None) is not None" instead. Here's a patch
to change that in ConfigObj (and pathutils).

Of course, that is subtly different, so you should verify it's ok. I
didn't run ConfigObj's test suite (unless it has no output and takes 1
second, in which case I did), but I did run Bazaar's test suite with
this change and nothing broke.
