Subject: add: use advise_if_enabled for ADVICE_ADD_EMPTY_PATHSPEC
X-Git-Tag: v2.45.0-rc0~37^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1028db00f7bc47e2cecda8a4a9967fcc05fffb48;p=thirdparty%2Fgit.git

add: use advise_if_enabled for ADVICE_ADD_EMPTY_PATHSPEC

Since 93b0d86aaf (git-add: error out when given no arguments.,
2006-12-20) we display a message when no arguments are given to "git
add".

Part of that message was converted to advice in bf66db37f1 (add: use
advise function to display hints, 2020-01-07).

Following the same line of reasoning as in the previous commit, it is
sensible to use advise_if_enabled() here.

Therefore, use advise_if_enabled() in builtin/add.c to show the
ADVICE_ADD_EMPTY_PATHSPEC advice, and don't bother checking there the
visibility of the advice or displaying the instruction on how to disable
it.

Also add a test for these messages, in order to detect a possible
change in them.
