Comment (by mmetz):

Unfortunately this is not reproducible (on Linux). What do you get with
shell-style output, i.e.

{{{
r.info map=Capefear_basin_CFS_area_dem05@capefearsh -g
}}}

The only explanation seems to be local modifications to
raster/r.info/main.c:L200.

Comment (by dnewcomb):

Running with shell style output gives the correct answer.
