I for one quite like the "highlight" style of pin cue -- it's unobtrusive and works well. Big square blobs would IMHO look ugly in printed output. However, it's quite true to point out that the cues don't work properly for zero-length pins, when a larger cue would be helpful for locating the pin.
How about drawing a box cue *only* when a pin is below a certain size?
