 migrating r.viewshed out of addons and into the main source tree? or is
 there still work to do?

 Maybe the r.los input option patt_map which is used as a mask, but from
 reading the r.los manual, the difference to setting a MASK is not clear to
 me.

 For GRASS 7, we are free to change module options, for GRASS 6, this
 patt_map option could be added for compatibility reasons, but the only
 effect would then be to print out a warning that a MASK should be used
 instead of patt_map=mask_map?
