r.statistics search for r.stats "fs" parameter

[marchesinivan]

r.statistics seems to use r.stats.

But the old "fs" parameter of r.stats is now changed to "separator", so r.statistics fails

In my case it was necessary to edit the file "run_cmd.c" (inside r.statistic folder) and move "fs=" to "separator="

Then just make and make install

Thanks for catching this. Fixed along with some more in r53295.
