Log:
df(1): Allow duplicate -l flags gracefully
Rather than producing a misleading error message when duplicate -l flags are
provided to df(1), simply ignore extra flags and proceed as if only one was
specified. This seems most reasonable given the usage for -l:
-l Only display information about locally-mounted file systems.
l and t flags still conflict, as before.
