 r.watershed launches a .seg or .ram version of itself from $GISBASE/etc/.
 It builds up a char string with options then runs the string via system().

 note in the above error messsage the " from the 1st arg and " from the end
 of the last arg have been stripped off. It seems that the quoting is
 greedy and the entire string is being treated as a the executable name?


 Hamish

 ps- will the .ram and .seg modules fail in GRASS 7 where uppercase option
 names are disallowed? (eg LS= and S=)

 pps- should G_convert_dirseps_to_host() be done in the G_gisbase() and
 G_gisdbase() functions instead or making the modules do it?
