 Here is what happens if you want to shrink region (grow < 0):

 {{{
 g.region -p raster=elevation
 g.region -p grow=-1
 # ERROR: Top must be larger than Bottom
 g.region -p grow=2
 g.region -p grow=-1
 g.region -p grow=-1
 g.region -p grow=-1
 # ERROR: Top must be larger than Bottom
 }}}

 When you have small depth (1 by default) you can't do `grow=-1`.

 ''Please, add milestone 7.6.''
