Now that our object/refname ambiguity test is much faster
(thanks to the previous commit), there is no reason for code
like cat-file --batch-check to turn it off. Here are
before and after timings with this patch (on git.git):
$ git rev-list --objects --all | cut -d' ' -f1 objects
[with flag]
$ best-of-five -i objects ./git cat-file --batch-check
real0m0.392s
user0m0.368s
sys 0m0.024s
[without flag, without speedup; i.e., pre-25fba78]
$ best-of-five -i objects ./git cat-file --batch-check
real0m1.652s
user0m0.904s
sys 0m0.748s
[without flag, with speedup]
$ best-of-five -i objects ./git cat-file --batch-check
real0m0.388s
user0m0.356s
sys 0m0.028s
So the new implementation does just as well as we did with
the flag turning the whole thing off (better actually, but
that is within the noise).
