Error when subsetting a mesh file in another directory

When trying to subset a mesh file in another directory, the resulting regional filename is incorrectly generated:

gwdo_region_auga_test/land> create_region conus.custom.pts /glade/scratch/mcurry/gwdo_region_auga_test/x1.40962.static.nc

This appears to be only on the subset_n_grid branch.
