It marks pin 1 of the resistor. 
My footprints also feature mark at pin 1 -- With thru hole technology the 
pad is square. With SMD footprints there is a kink at the corner in the 
silk frame. This facilitates probing for signals during the inevitable 
debug stage. I know which side of the resistor I need to stab with my 
scope probe if am interested in that particular spot in the schematic.
SMD resistor solder joints are often the more convenient to probe than 
that tiny output pin that sits just next to Vcc.

I adopted these polarized resistor symbols from my former boss.
