revset-rangeset: call 'getset' on a 'fullreposet' Calling 'baseset(repo.changelog)' builds a list for all revisions in the repo. And we already have the lazy and efficient 'fullreposet' class for this purpose. This gives us the usual benefit ofs the fullreposet: revset) 10:100 before) wall 0.002774 comb 0.000000 user 0.000000 sys 0.000000 (best of 797) after) wall 0.001977 comb 0.000000 user 0.000000 sys 0.000000 (best of 1244) revset) parents(10):parents(100) before) wall 0.005054 comb 0.000000 user 0.000000 sys 0.000000 (best of 481) after) wall 0.002060 comb 0.000000 user 0.000000 sys 0.000000 (best of 1056)
