Using header lines requires stateful parsing, which complicates
matters.

For machine readable output, provide an option to output either
qualified or unqualified names. Qualified names should be the default,
IMHO. Unqualified names are a convenience for interactive use, to save
the user from having to type @mapset every time. Where map names are
passed within or between programs, qualified names should always be
used.
