Aspell needs to parse the "-vv" command-line argument, and Emacs
launched in batch mode cannot do that.  Or I did not manage to make it.

I am not intentionally ignoring your suggestions, some of my responses
got lost while moving from emacs-devel to the bug tracker.

Fixed.

Fixed.

This is not a file path.  This is just a string which looks like a file
path.  If something tries to access this as if it is a path during the
execution of the test, this is an error.
