gforthmi instructions confused regarding relocatability

[Ethan Gardener]

In the gforth documentation, at the bottom of section 13.5.1, are some confused 
statements. To quote:

> A special doubly indirect threaded version of the gforth executable is used 
> for creating the non-relocatable images; you can pass the exact filename of 
> this executable through the environment variable GFORTHD (default: 
> gforth-ditc); if you pass a version that is not doubly indirect threaded, you 
> will not get a fully relocatable image, but a data-relocatable image (because 
> there is no code address offset). The normal gforth executable is used for 
> creating the relocatable image; you can pass the exact filename of this 
> executable through the environment variable GFORTH. 

I think "not get a fully relocatable image," should be "not get a 
non-relocatable image,".
