We probably should add some instructions for the the user on when the -n 
switch could help. Working with global maps, for instance, bordwalk() does 
not help because the whole input map has to be loaded into memory anyway 
and there is nothing to trim from the output either.

To the error message 'Input area is outside current region' given by 
bordwalk(), we could add something like 'Check your current region 
settings, or if this is a global map, try the -n switch' 

The message sometimes erronously is given by bordwalk() on global->global
projections (I should try to fix that). Sometimes the user (at least
happens to me) forgot that he has zoomed in on a smaller region in the
location and really is outside the input map. Sometimes the users's
default region borders are just guesswork and completely wrong.
