matchparen: do not use hard-coded match id (#13393) Commit: https://github.com/vim/vim/commit/d3e277f279ed628809eb6857ea3ebcfca566ca2a Author: Christian Brabandt <cb@256bit.org> Date: Sat Oct 21 11:06:50 2023 +0200 matchparen: do not use hard-coded match id (https://github.com/vim/vim/issues/13393) * matchparen: do not use hard-coded match id Instead of using the hard-coded match id 3, which may also be used by other plugins, let the matchparen plugin use whatever ids are automatically returned when calling matchaddpos(). For backwards-compatibility, keep the `:3match` call, which will still use the hard-coded id 3 (as mentioned in :h :3match). closes: #13381 Signed-off-by: Christian Brabandt <cb@256bit.org>
