shell completion '-t' for extensions prompt

[Freed-Wu]

Now, the shell completion -t(e.g. zsh) is as following:

❯ rg -t<Tab>
file type
agda          cabal         csv           fidl          hbs           license       minified      po            robot         sv            typoscript    z
...

In the code, it truncate :* of the output of rg --type-list

❯ rg --type-list|head -n1
agda: *.agda, *.lagda

How about adding the extension information? Like this:

❯ rg -t<Tab>
file type
agda     *.agda,*.lagda
aidl     *.aidl
...

It should can be realized, because zsh use (agda aidl) to provide the completion without prompt information, and use (agda\:*.agda,*.lagda aidl\:*.aidl) to provide the completion with prompt information.

Just like fd -t<Tab>

I think the current behavior is ideal. Otherwise it becomes way too noisy. If you want to see the extensions for each type, then I think needing to run rg --type-list separate is fine.

zsh has a standard style called extra-verbose that can be used for stuff like this. _rg_types could support it with a small modification, and then users who want the more elaborate completion results can turn them on in their shell profile with zstyle.

Maybe the visual/maintenance burden still isn't worth it, idk, but i could put a PR together if you did want to provide the option

Oh I would be okay with that! Good call.
