 Small issue for GRASS data transfer via "pack" format:

 In case that a user doesn't use a self-explaining file name, it may not be
 obvious if r.unpack or v.unpack has to be used. In case of running the
 wrong command, an "ugly" error message appears rather than telling the
 user to apply the other respective unpack command.

 Solution: simply check for the presence of 'mapname/cell' or
 'mapname/coor' and generate a user message if the wrong content was
 detected.

 Message suggestions:

 {{{
 #r.unpack

 grass.fatal(_("This GRASS GIS pack file contains vector data. Use v.unpack
 to unpack <%s>) % map_name))

 #v.unpack

 grass.fatal(_("This GRASS GIS pack file contains raster data. Use r.unpack
 to unpack <%s>) % map_name))
 }}}
