From 56e743426b183d8aea8f4caa363e7f3c7da27278 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Sun, 2 Aug 2020 03:14:27 +0000 Subject: [PATCH] merge-recursive: fix unclear and outright wrong comments Commits 7c0a6c8e47 ("merge-recursive: move some definitions around to clean up the header", 2019-08-17), and b4db8a2b76 ("merge-recursive: remove useless parameter in merge_trees()", 2019-08-17) added some useful documentation to the functions, but had a few places where the new comments were unclear or even misleading. Fix those comments.
