I'm running v.trim on a map generated from the Census Bureau's TIGER files,
using a trim factor of 0.0 because I only want to eliminate unnecessary
nodes, not remove any lines.  The output file, however, has all single
polygon islands missing.  I've tried it in GRASS 4.0 on both a Sun IPC and
Intel 386 system with the same results.

Why?
