Doesn't help if I want to generate the *cap file before init.sh is  
run, since the user hasn't selected a map yet.  I thought about  
trying a dummy location like the demolocation, but that would have to  
be installed with the binary.

I came up with this possibility - in init.sh, after it gets a valid  
mapset from the user (and all the needed vars are set):

--- init.sh-orig        2007-05-11 13:58:54.000000000 -0500
+++ init.sh     2007-05-11 13:56:38.000000000 -0500

This should be safe - it should not get run on the *caps installed  
with the GRASS binary (though if a user sets either to be the binary  
copy, it will try to), but only when either or both env vars are set  
and the file doesn't exist.  It will give the user a start for adding  
other fonts manually, or cleaning up possible mistakes.
