I actually use the -a option.  But it hasn't fully worked since 10.0-RELEASE.
See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205580
Still present in 12.2-BETA2.

I maintain a local set of patches that solves this bug, but it requires the
installation of the tradcpp port/package so I've never shared them, but
would if someone wants them.
