* [bash] bring fzf’s own bash completion up to date

This orders and groups completed options and values in just as they appear in
the code respectively, for some option values, as they’d be printed in the
`--help`-output.

It does not add support for completion of `:` right after values that support an
optional `:some-further-value` postfix.
Neither does it add support for the `--option=value`-style.

* [bash] drop unnecessary code in handling `history`

Presumably, the dropped code is not needed for any effect, thus drop it.
