Modified Files:
src/etc/rc.d: staticroute
src/share/man/man5: route.conf.5
Log Message:
Add the ability for staticroute to evaluate lines from /etc/route.conf
as shell script fragments, add example to the route.conf man page of
evaluating variables.
Remove route.conf man page statement that staticroute is enabled in
rc.conf since that's incorrect.
Wrap the staticroute while in parens, per <apb> & <christos>, and
quote all the arguments for the evals.
