 Replying to [comment:4 perk]:

 > > 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?

 > This should be self-contained.  "currentlinejoin" puts the current line
 join style on the Postcript stack, "1 setlinejoin" sets the join style to
 rounded, "stroke" draws the current path (does not affect the stack), and
 the final "setlinejoin" uses the value put on the stack earlier to return
 the join style to the previous value.

 The normal way to make temporary changes to the rendering state is with
 gsave/grestore, e.g.:

 {{{
 gsave 1 setlinejoin stroke grestore
 }}}
