From 348f199b2d9250a82453323c90b7e8d3d9462220 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Sat, 13 Feb 2010 22:28:35 +0100 Subject: [PATCH] builtin-notes: Refactor handling of -F option to allow combining -m and -F By moving the -F option handling into a separate function (parse_file_arg), we can start allowing several -F options, and mixed usage of -m and -F options. Each -m/-F given appends to the note message, in the order they are given on the command-line. The patch includes tests verifying correct behaviour of the new functionality.
