From bebf5c04767b3c67dadfa8b65e6f0ceb258f6b83 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Sun, 9 Nov 2014 13:30:49 +0100 Subject: builtin/notes: improve naming In preparation for some needed refactoring, rename struct msg_arg to struct note_data, and rename its instances from "msg" to "d" (also removing some unnecessary parentheses). The 'msg_arg' name was inherited from tag.c, but is not really a good name for the contents of a note. Also rename write_note_data() to copy_obj_to_fd(), which more aptly describes what it actually does: Copying the contents of a git object (given by its SHA1) into a given file descriptor.
