[GRASS5] 5.7 - GIS manager - zoom and pan - change term to execute in d.m.tcl

[Michael Barton]

Could this somehow be worked into the init.sh script so as to do a tiny bit
to keep multiple file clutter to a minimum? If not I'd suggest to put it in
gui.tcl as a procedure, or barring that in $GISBASE/etc/d.m/script except
that it seems like some people need it for the command line in a few cases
if I understood some of the comments earlier.
