Comment (by martinl):

 Should be fixed in r74452:

 {{{
 r.watershed elev=dem
 ...
 ERROR: At least one of the following options is required: <accumulation>,
 <tci>, <spi>, <drainage>, <basin>, <stream>, <half_basin>, <length_slope>
 and <slope_steepness>
 }}}

 Also `threshold` check improved:

 {{{
 r.watershed elev=dem basin=x
 ...
 ERROR: Option <basin> requires <threshold>
 }}}
