The -n flag comes from r.proj and is explained as such in the r.proj man 
page:

"When reprojecting whole-world maps the user should disable map-trimming 
with the -n flag. Trimming is not useful here because the module has the 
whole map in memory anyway. Besides that, world "edges" are hard (or 
impossible) to find in projections other than latitude-longitude so 
results may be odd with trimming."
