Zbigniew Jędrzejewski-Szmek a60f12202f cgls: fix/update/restore the handling of --xattr and --cgroup-id
This is a bit tricky. Previously, the --help string said
"-x --xattr=BOOL", which normally means that '-x BOOL' and '--xattr BOOL'
and '--xattr=BOOL' are all accepted and equivalent. But actually only
the third form was accepted. '-x' should have been and is now documented
as "Same as --xattr=true". The man page tried to explain this, but not
very strongly. So update the man page to have more emphasis and restore
the special behaviour for -x and -c. This is a on old program, so I
think in this case, maintaining compatiblity in behaviour is important.

<title>Description</title>
<para><command>systemd-cgls</command> recursively shows the
contents of the selected Linux control group hierarchy in a tree.
If arguments are specified, shows all member processes of the
specified control groups plus all their subgroups and their
members. The control groups may either be specified by their full
file paths or are assumed in the systemd control group hierarchy.
If no argument is specified and the current working directory is
beneath the control group mount point
<filename>/sys/fs/cgroup/</filename>, shows the contents of the
control group the working directory refers to. Otherwise, the full
systemd control group hierarchy is shown.</para>
<para>By default, empty control groups are not shown.</para>
