Subject: [PATCH 02/30] notes & match-trees: use name_entry's "pathlen" member

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Mon, 8 Mar 2021 16:06:22 +0100

Change code that was doing a strlen() on the "path" from a name_entry
struct to instead use the pathlen given to us by decode_tree_entry().
