Well the stack overflow answer says non-GNU sed doesn't support the single-command version, and needs a two-command version. reinplace doesn't support executing multiple commands. You could run a two-command sed manually (with system, not reinplace). Or maybe you can use awk, or an ed script. I can't remember anybody asking for this functionality (replace first occurrence) before, so that's why there isn't an easy way to do it.
