I tend to think that -L,-20 is a sloppy spelling of -L1,-20
(i.e. anything omitted gets reasonable default, and for something
that specifies both ends, i.e. "<begin>,<end>", the beginning and
the end of the file would be such reasonable default, respectively),
and as such I would imagine that the user would expect the same
behaviour as -L1,-20. If the longhand version gives only the first
line (i.e. show up to 20 lines ending at line #1), I'd say that
sounds sensible.
Or does -L1,-20 show nothing and consider the input invalid? If so,
then sure, -L,-20 should also be an invalid input.
