[vis-open] Handle filenames with spaces and tabs.

We still don't handle filenames that contain newlines, but we're
pressing against the limits of what portable POSIX shell can do. Besides
which, we're ultimately plumbing filenames into vis-menu which uses
newlines as a delimiter *anyway*, so there's not much we can do.
