[GRASS-dev] i.landsat.rgb -p after using i.fusion.brovey

[Otto Dassau]

Hi, 

i.landsat.rgb -p fails for me with maps created with i.fusion.brovey:
line 138: [: 47.9603: integer expression expected
[...]

Attached you find the small changes that make it work at least for me again. 

Regards,
 Otto
