Default <tree-ish> of HEAD when nothing is specified is certainly something I wanted. To be honest, I wanted it for rev-list too. Despite dozens if not hundreds of times of typing 'git ls-tree -r' or 'git rev-list' expecting to see the results for HEAD (just as git log does), and getting git's error message reminding me that I need to specify HEAD, I can't seem to get it through my head to remember that I need to specify it. > I'd prefer *not* to have such a DWIM in a command like ls-tree, aka > plumbing commands, where predictability is worth 1000 times more > than ease of typing. Fair enough. However, what if no <tree-ish> or <path> are specified, though -- would you be okay with the HEAD being assumed instead of erroring out in that case?
