Subject: [PATCH 19/30] tree-walk.h API: formatting changes for subsequent commit

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Mon, 8 Mar 2021 16:06:39 +0100

Do formatting (mainly whitespace) changes of code around the
get_tree_entry() function to make a subsequent change where we'll add
a sister function easier to read.
