[systemd-devel] [PATCH] systemctl-completion: always invoke with --no-legend

[Dave Reisner]

In the case of completion for the 'restart' verb, passing the invalid
unit name (the colums header) causes completion to cease functioning
entirely, with the error:

  Failed to issue method call: Unit name UNIT is not valid.

This adds a small wrapper function for systemctl which can have common
options added to it.
