>Description:
When configuring software in /etc/rc.conf I sometimes find that I want to append something to <software>_flags instead of overwriting it. This may be the case for long lines or lines where the defaults are sensible but just missing stuff.

For example in the mailgraph rc-script, the default is:
: ${mailgraph_flags="--logfile /var/log/maillog --daemon-rrd=/var/db/mailgraph --ignore-localhost --daemon --daemon-pid=${mailgraph_pidfile}"

I just want the '--rbl-is-spam' flag added. In this case another problem occurs, predefined variables are used (the pidfile). So that would mean I need to define both or define them in one go.
>How-To-Repeat:

>Fix:
I propose to have /etc/rc.subr line 594 (eval rc_flags=\$${name}_flags) expanded to include something like \$${name}_flags_append
