Manjaro not detected as Arch Linux

[JOJ0]

Manjaro is not correctly detected as being an arch-like distro. I think it can be fixed like this in mppinit:

if [ -f /etc/os-release ]
then
  . /etc/os-release
  [ "${ID}" == "debian" ] || [ "${ID_LIKE}" == "debian" ] && debian=1
  [ "${ID}" == "arch" ] || [ "${ID_LIKE}" == "arch" ] && arch=1
  [ "${ID}" == "centos" ] && centos=1
  [ "${ID}" == "fedora" ] && fedora=1
else
