[PATCH v2] tree-walk.h: fix incorrect API comment
From: Elijah Newren <newren@gmail.com>
When commit 50ddb089ff68 (tree-walk.c: remove the_repo from get_tree_entry(), 2019-06-27) added an extra parameter to get_tree_entry(), it did not fix the ordering comment about the meaning of the parameters. Rather than just changing "third"->"fourth" and "fourth"->"fifth", give the paramemters meaningful names (or actually, just take the existing names from the get_tree_entry() definition in the tree-walk.c file) and while at it, tweak the rest of the description to incorporate the other parameter names as well.
