twistedchecker fails when it encounters emacs backup files

[ghost]

I ran it on my twisted branch and got this

(twistedchecker)[richard@zorin add-setup-1084552]$ twistedchecker twisted
Traceback (most recent call last):
  File "/home/richard/.virtualenvs/twistedchecker/bin/twistedchecker", line 10, in <module>
    Runner().run(sys.argv[1:])

    findPatternsInFile(open(pathFile).read(), finder)
IOError: [Errno 2] No such file or directory: '/home/richard/projects/Twisted/branches/static-path-3765/twisted/web/.#static.py'

It should only examine actual python modules.

@wallrj I took a look at this but pylint is ugly here.

The problem is that pylint only ignores explicit file or folder paths... without a filemask and does not provide a hook into file filtering code

filtering is done in pylint.utils.expand_modules based on the config.black_list which populated by the --ignore argument.

Can you just change emacs setting to backup files in `.static.py~' format? or maybe you can configure it to make backup outside of source folder?
