Title:
  systemd does not work with escaped paths

Status in systemd package in Ubuntu:
  New

Bug description:
  Cannot start systemd service using paths with spaces:

  systemd unit file content:
  [Unit]
  Description=LocalView UPS monitoring service

  [Service]
  Type=forking
  WorkingDirectory=/usr-Socomec\x20UPS-LocalView
  ExecStart=/usr-Socomec\x20UPS-LocalView-StartApp.sh

  [Install]
  WantedBy=multi-user.target

  Although systemd-escape converts "/usr/Socomec UPS/LocalView" path to usr-Socomec\x20UPS-LocalView,
  systemd complains it is not an absolute path when the '/' in front of it is missing in the unit file:

  systemd[1]: /etc/systemd/system/localview.service:6: Working directory
  path 'usr-Socomec\x20UPS-LocalView' is not absolute.

  The same applies for ExecStart entry.

  When the syntax check was satisfied I tried to run the service:

  systemd[11574]: localview.service: Changing to the requested working directory failed: No such file or directory
  systemd[11574]: localview.service: Failed at step CHDIR spawning /usr-Socomec UPS-LocalView-StartApp.sh: No such file or directory

  # ll "/usr/Socomec UPS/LocalView/StartApp.sh"
  -rwx--x--x 1 root root 220 kvě 26 17:27 '/usr/Socomec UPS/LocalView/StartApp.sh'*

  Unescaped path in the unit file obviously does not work either.
