I would suggest that since this is in the 5 nanometer range, and WIND is
seemingly stored to `%.14g` (or does that happen when reading the vector's
&window?), that we verify that `printf(%.15g)` is used when writing the
WIND file and then if needed use GRASS_EPSILON to test.
I would suggest ignoring such corner cases in the code, keep using fast >=
tests, and recommend in the docs that `g.region vect=` should be used with
the `-a and res=` options in most cases.
I'm not sure where the %.14g is coming from, as lib/gis/wind_format.c
writes using %.15g.
