The stroke fonts don't have descriptive long names in the above example 
(just a copy of the short name) - you may need to run "g.mkfontcap -o" to 
overwrite your fontcap file. I changed it so it won't automatically 
overwrite it when re-compiling, as I thought that was a bad idea in case 
someone might have manually edited their file (e.g. to include only the 
fonts they commonly used, in their preferred order ;)

But maybe sorting by short name is a better idea than long name, and it 
should be up to the GUI to sort on long name if that's a better option for 
it - the patch below will make the sort operate on the short name (you 
will need to re-run g.mkfontcap -o again):

About the d.font -L output - I'd been thinking (shortly before Glynn 
implemented it) that it might be quite neat to have some kind of 
font_info() function that could be passed the name of a font from 
R_font_list(), and it would return a GFONT_CAP struct (defined in 
grass/freetypecap.h) with all the font info - and then d.font or other 
programs could take the font info from the members of this struct and 
format the output as they saw fit. But perhaps this would have been 
over-complicated to implement in the existing driver structure - I'm 
really not sure and also not sure how much use if any it would be for 
other modules.
