As you can see, it did ignore the 'file!abc' and 'file#abc' files
correctly. Those don't need to be quoted because # and ! are only
special at the beginning.
Most of the other files are not ignored properly because their
special characters need to be escaped. For * it's the other way
round: while it does hide 'abc*def', it also hides 'abc_def',
which we don't want.
