[GRASS-dev] more interesting failure for reading fp_range of a NULL map

[Yann Chemin]

Hi,

dealing with large amount of maps, some of them process to NULL on all
pixels.
when accessing fp_range in cell_misc, the file is empty, thus returning
such an error:

WARNING: Unable to read fp range file for <NULL_map_test at PERMANENT>

While I understand this is undefined because of all pixels being NULL,
would it be possible to have a more interesting output?

This could help in screening NULL maps too...

Thank you,
Yann
