Re: woman doesn't work if current buffer's directory doesn't exist

[Richard Stallman]

    There's no ``best way'', it depends on what code calls call-process.
    In some cases, you could bind default-directory to something sensible
    (e.g., invocation-directory), in others you _must_ fail, because the
    command arguments could use something like "./foo/bar" which precludes
    us from changing directories.

That is a good point.  Could you fix woman?
