Subject: [PATCH] rev-parse: don't trim bisect refnames
Using for_each_ref_in() with a full refname has always been a questionable practice, but it became an error with b9c8e7f2fb (prefix_ref_iterator: don't trim too much, 2017-05-22), making "git rev-parse --bisect" pretty reliably show a BUG.
Commit 03df567fbf (for_each_bisect_ref(): don't trim refnames, 2017-06-18) fixed this case for revision.c, but rev-parse handles this option on its own. We can use the same solution here (and piggy-back on its test).
