[GRASS-dev] Unexpected EVI range from "i.vi"

[Nikos Alexandris]

Markus, and whom this is of interest,

do you care for a small diff for the manual?

Like,

- replace the reference (as you suggested)
- mention that "EVI is not consistent across different sensors due to its 
requirement for a blue-band input" [0]
