This one turned out to be more effort than I had originally anticipated. We had a bug report requesting that zapping a wand of digging laterally while in a pit should dig beside you. That seemed like a reasonable enough request, but this ended up with the following results: - needed to check where this should not be permitted, or at least where there should be special-case code because there is something such as furniture on the surface above the dig point. - now tracks conjoined pits through new fields in the trap structure, hence the pathlevel increment. The array of 8 boolean values represents each of the 8 directions around a pit. - Previously, pits could be adjacent to each other as two individual pits, in which case moving between them results in a fall as you went into the next pit. That behavior is preserved. - Pits created either by zapping a wand of digging laterally while in a pit, or by "clearing debris" between two adjacent pits via a pick-axe, sets the conjoined fields for those two pits. You cannot create a brand new adjacent pit via pick-axe, only with the wand. - The hero can pass between conjoined pits without falling. - dighole() was hijacked for adjacent pit digging, so the ability to pass coordinates to it and its downstream functions was added (dig_up_grave() for example). dighole() does pretty much everything appropriately for this adjacent digging, more so than calling digactualhole() directly. - moving into a conjoined pit that has spikes still does damage, but less so that "falling" into the spiked pit, and you "step on" the spikes rather than falling into them. - Not done: should pits with the conjoined fields set be referred to as 'trenches' rather than pits in messages and identifications?
