Comment:

 nice to finally see a solution for this, thanks.


 before applying the patch I would like to ask about possible side effects
 -- does the "currentlinejoin 1 setlinejoin stroke setlinejoin" part need
 to be swiched off after drawing the labels, or will it be self contained?

 could a similar technique be used to connect .eps pattern tiles?
 eg broken lines:  http://grass.osgeo.org/wiki/Psmap_flooding_example


 you might also see that d.labels does not do very well with larger values
 for the highlight width. In that case I guess the solution is to also
 smear the color using the "knight's move" or similar, not just the 8
 cardinal+ordinal directions.

 svn bug? (PostScript is ASCII)


 fwiw, trac does nice markup when you click on the .diff file.
