That should give you an error ... does it?



anything but

v.distance help
v.distance --help

should give you an error. 'help' is only scanned for as the first
arguement, anything after the 'help' is ignored.

The error should show the usage screen though, so little harm.


If some text is given, the parser assumes it is the first arguement,
e.g.

d.erase color=blue
d.erase blue


compare 
 d.erase blue help
with 
 d.erase help blue
