Initial Comment:
Hi,

It would be nice if d.legend could look for "map=-" and if so take legend cat and color info from stdin. That way vector maps and custom legends could be made without resorting to tricks like making a dummy raster file to hold that info.

If data is fed from stdin (signaled by map=-) create categorical legend
using that data. Data format: "cat|label|color"

e.g.

d.legend -m map="-" <<EOF
1|Main Street|255:0:0
2|Elm Street|0:255:0
3|Old Coach Road|0:0:255
EOF

In this way d.legend could work as a system module by the GUI instead of
a user module, and be useful for non-raster tasks too.
