The purpose was interactive use from the command line I suppose, so for
these cases users can set a convenient alias for sending the signal or a
prefix command to use with the display commands (to call the command and
then send the signal) like `ni d.rast elevation` where `ni` is the
command/alias. Adding something similar to a script has even a smaller
overhead, although it too requires you making sure it happens every time
instead of the one-time GRASS_NOTIFY settings. (I'm assuming here that
signal handling in the imgview programs is not removed.)
