Yes. Unfortunately, the historical development of this editor left it
with two different "g" commands.
"g" select lines globally within the range. This one can be negated.
"g" perform operations globally within the line.
As sort of pointed out by Jim Sack, if the region of interest is all
lines, you don't need both the initial "%" and the "g" since "%" ==
all lines is implied by an otherwise unspecified "g".
The "g!" inversion of the selection was originally "v" but this seems
to have been redefined to be something else in vim. At least
according to my quick look through the _Vi Improved_ book.
