Subject: PATCH: fix .zle.sgr for empty sequences
Date: Sat, 09 Mar 2024 23:30:47 +0100 [thread overview]
Message-ID: <61192-1710023447.936507@Vf9U.zuLW.VgB3> (raw)
This fixes .zle.sgr from the new hlgroups module to return "0" when the
sequence is empty. In particular \e[m typically works them same as \e[0m
so we want to return the 0 in that case.
