[systemd-devel] [PATCHv2] man: improve wording of systemctl's --after/--before

[Jason St. John]

Commit 4a77ca7 was an attempt at fixing the wording of --after and --before,
but the new wording was unclear.

Split the combined --after/--before section into a separate section for
each, explicitly state what each option does, and add information about
how these lists are generated.
