Hi,

FWIW, a single layer board issue ... I think it is problem for pins with 
various distances in between (only), and not for pads with a solder 
bridge (one can only "bridge" a handful of mil with solder, so there is 
a "fixed" span distance).

I use two single pin symbols in the schematic and connect (and place a 
text "wire bridge").

I use two single pin footprints in the pcb layout and draw the "wire" on 
a separate layer and silkscreen.

Fab'ed two layer boards are not that much extra in cost, maybe even 
cheaper ... so only unless the board is DIY.

My two cents ... enjoy ;-)

Kind regards,

Bert Timmerman.
