* doc/runscripts.html: typo; openssh needs absolute path (thx Kevin Berry);

    exec into dhcpcd.
  * uidgid.c, uidgid.h, chpst.c: support colon-separated list of groups.
  * sv.c: utilize optional ./check script in service directory to check for
    availablity of service.
  * runsv.c: wait_pid() might be interupted.
  * man/chpst.8, man/sv.8: adapt.
