docs: manpage warnings: cannot adjust line

[reinerh]

While building a package of a current git snapshot, I noticed a linter warning for the manpage:

$ MANWIDTH=80 man --warnings -l src/man/firejail.txt >/dev/null
troff: <standard input>:389: warning [p 5, 10.7i]: cannot adjust line
troff: <standard input>:502: warning [p 7, 4.3i]: cannot adjust line

The lines are:

$ firejail --dbus-system=filter --dbus-system.broadcast=org.freedesktop.Notifications=org.freedesktop.Notifications.*@/org/freedesktop/Notifications

and

$ firejail --dbus-user=filter --dbus-user.broadcast=org.freedesktop.Notifications=org.freedesktop.Notifications.*@/org/freedesktop/Notifications

I'm not completely sure what the reason is, but I guess the last argument is a bit long for displaying and it doesn't know how to split it up.

You can enclose it in .in +/-.3i, ll -/+.5i to shift, I think:

       --dbus-user.broadcast=name=[member][@path]
              ...........................................................
              interfaces.  The path may have a /* suffix to indicate all objects  underneath  it,  in‐
              cluding itself.  Omitting the interface member or the object path will match all members
              and object paths, respectively.

              Example:
                 $  firejail  --dbus-user=filter  --dbus-user.broadcast=org.freedesktop.Notifica‐
                 tions=org.freedesktop.Notifications.*@/org/freedesktop/Notifications

or break it like:

              Example:
                 $  firejail  --dbus-user=filter  --dbus-
                     user.broadcast=org.freedesktop.Notifications=org.freedesktop.Notifications.*@/org/freedesktop/Notifications

Without:

              Example:
              $       firejail      --dbus-user=filter      --dbus-user.call=org.freedesktop.Notifica‐
              tions=org.freedesktop.Notifications.*@/org/freedesktop/Notifications

all fixed, I braked the lines with "\"
