Summary0004000: Dwarf Digging Priority ignores depth
DescriptionI build a 3 level deep moat and flood only the bottom level. But designating multiple levels of channels the dwarves dig down immediately to the lowest level, dig around a bit then proceed back up only to have cave ins. While not severe it greatly inhibits digging shafts of 2x2 or larger. This makes it difficult to queue up a digger dwarf to dig down a 10 z depth 3x3 shaft for instance.
Steps To Reproducechannel a moat of 3 width (make a donut for instance)
Go down a level
channel the same moat
Watch in horror...
Additional InformationThis is minor in the fact that if we are trying to queue up (for instance using quickfort) a fortress it would be nice that the dwarves first complete the digging on the current level before going down.

Programatically it looks like they are running through a nested loop where it goes

for each y
  for each x
   for each z


to an extent. Where as doing
for each z
 for each x
  for each y

you resolve the cave in issue (simplification). Altering this may also resolved 3x3 stairwells which allow each level to be complete before descending the next level.

I never actually noticed this until .19 since I A: started building moats and B: starting using quickfort for build macros.

Dwarf pathfinding is prioritized strangely is the main gist of your report I gather, which is covered under 0001463.
