[GRASS5] r.sun parameter descriptions

[Hamish]

Hi,

the following change improved the r.sun parameter descriptions somewhat:

grass6/raster/r.sun/main.c
  http://grass.itc.it/pipermail/grass-commit/2005-March/016953.html


but left many option desciptions ending with "[-]" (e.g. albedo).

Should these be replaced with [0-1] ?

add to opt->options or (0 <= x <= 1) checks in the C code?


Anyone have plans or thoughts about migrating to the SOLPOS algorithm?
What sort of improvement would this bring? i.e. is the difference large
enough to matter in a practical sense or is it more an academic matter
of making the model as correct as it can be? 



thanks,
Hamish
