If the history is empty (or if HISTSIZE is 1) running `fc -l' produces an error:
$ history -c
$ fc -l
bash: fc: history specification out of range
I'm not sure this is necessary, since other instances of `first' and
`last' being outside of the saved history range don't produce an
error. Also the `history' command doesn't have this behavior:
$ history -c
$ history
1 history
As a special case, `fc -l -0' usually prints itself but not in the
empty history (or HISTSIZE=1) case.
