functions foo doesn't show --wraps flag

[lilyball]

When a function is defined with --wraps, the output of functions (and therefore, the output of type) does not include the --wrapsflag:

> function foo --wraps git; git; end
> functions foo
function foo
    git;
end

Currently you can specify --wraps in complete and function, but we don't track where it came from. This is a little bad because redefining a function doesn't clear any '--wraps' from the previous function definition. We ought to track where the --wraps comes from, so we can both display it and clear it.

Additionally to not showing the --wraps part it is also dropped when using funcsave to persist the function. So is this value persisted anywhere else?

I am using the same config on multiple machines and I only share (most parts of) ~/.config/fish directory and not the directory where the completions are stored. I am fairly new to fish and as I am still setting this up on all machines I have not yet checked whether the completion carries on to the other machines without redefining the function adding the --wraps part back in.

Part of what's funny about this is that --wraps can come about through either function definitions or completions. We need to be able to tease these apart I think.

Any news about this?

@ridiculousfish Do you have any idea where the problem lies so I can attempt to fix it?

Noting here that #2466 and #5843 show this can actually cause real functional issues, not just technically wrong output: Using funcsave to save a function will not show the right completions on the next session.

I decided it doesn't matter whether the wraps comes from complete or function, let's just always print it.
