Yeah, that's something that's missing right now. It is my hope to have
ps.map's colortable instruction and d.legend query the new raster map
units metadata and display the text if it's there. (raster units
metadata is a new feature for GRASS 6.3; see r.support and r.info)

For now you have to use d.text or ps.map's text instruction to place the
units text manually. It's a pain, but hopefully I'll have a chance soon
to code it in properly.


semi-related: I think I'll have to revert the right-justified d.legend
text back to left-justified as it comes up all strange if the user has
set the font to be a proportional TTF, which will be a common thing with
the newer GUIs.
