Initial Comment:
Hi, 

I have just experienced, how expensive it can be, to write a WARNING out for every point, when buffering. I try to build simple buffers (only 8 points needed) around a lot of points - in one case 370.000 - and for the reason I choose a high tolerance value (to be sure, it will be reset to the max allowed one). THis works, but takes unbelievably long with all the warnings:
"WARNING: The tolerance was reset to ..."

Now I have commented out the warning in main.c of v.buffer, and suddenly it is running like mad (30 seconds instead of over 10 minutes). So maybe it would be nice to :
- either add another switch to turn off this warning
- or include it under the "--quiet" option (NO warning if "--quiet" set).
