    Fix bug in TeX-command-sequence
    
    * tex-buf.el (TeX-command-sequence): Ask for TeX-master if unknown,
    otherwise running this function on a file without a known `TeX-master'
    will result in `TeX-master' being automatically set to "<none>" at some
    point.
    (TeX-region-file): Add a third compatibility argument and update
    docstring accordingly.
