Are all icons from other GPL or BSD/MIT projects fair game?

If you do, please make that something like $(GISBASE)/etc/gui/icons
It is already confusing that the vector point symbols are often called
icons ($GISBASE/etc/symbol). Let's not make it any worse.

This should already be the case in most modules. It is controlled by the
order in which the options are defined in the source code. Sometimes it
happens this way out of oversight or modification*, other times it is on
purpose or conforming to a more import design consideration**.

[*] e.g. g.filename. I've just moved the newly optional mapset= option
to appear last.

[**] e.g. 'v.in.ascii [in=] out=' is best I think.

careful, often a flag is the only command line option desired. Or none.

d.barscale -m
d.erase
