Use TAB in -- command to complete partial option name

[gwsw]

When setting options with long names, it would be nice to not have to type the whole name. TAB could cycle through option names in the -- command, similar to the way it works on filenames in the :e command.

Warp has already partial supported completion for less

Thanks. To be clear, this issue is about adding TAB completion to the -- command inside less, not to the shell, since less cannot affect how the user's shell behaves.

Warp is not another shell, but a "modern, Rust-based terminal with AI built. Completions will suggest commands, option names, and path parameters".
2024: I don't know how this works, it's AI.
