New description:
Create a file, attach it in a Sage session, then delete/move the file.
Sage does not like this - and every command results in `OSError: [Errno 2]
No such file or directory: '/path/to/attached/file.py`. It won't even let
you detach the file.
At the moment before each command is executed, Sage checks to see if any
attached files have been modified. Presumably instead it should except
this error, remove the file from the list of attached files, and inform
the user.

Comment(by ltw):
Here is a new patch that detaches inaccessible files and issues warnings.
Doctests for the re-written function `modified_attached_files` have been
overhauled as well. Please review!
