From 5c4f55f1f62b64f530bd135e5b248ceba7b95708 Mon Sep 17 00:00:00 2001 From: Heba Waly Date: Tue, 17 Dec 2019 09:17:22 +0000 Subject: [PATCH] commit: honor advice.statusHints when rejecting an empty commit In ea9882bfc4 (commit: disable status hints when writing to COMMIT_EDITMSG, 2013-09-12) the intent was to disable status hints when writing to COMMIT_EDITMSG, because giving the hints in the "git status" like output in the commit message template are too late to be useful (they say things like "'git add' to stage", but that is only possible after aborting the current "git commit" session). But there is one case that the hints can be useful: When the current attempt to commit is rejected because no change is recorded in the index. The message is given and "git commit" errors out, so the hints can immediately be followed by the user. Teach the codepath to honor the configuration variable.
