[GRASSLIST:4180] Addition to "redirecting v.what results..."

[Andrew]

Sorry, I forgot to specify that the result is redirected to file if
batch-grass.sh is run on the command line, but I get the errors when
batch-grass is run from another programme (Pascal).
By the way, batch-grass works fine using Exec in Pascal, the errors are
generated when I try redirect the result to file using batch-grass.

Hope that makes more sense now
Andrew
