Add 'function_wrap' wrap shortcut

[whtns]

Add a function called 'function_wrap' that places parentheses around a given text selection and moves to cursor to a position immediately before the newly added parentheses

I often would like to wrap a text selection in a function call. One extremely common case is a call to View for a given R object from the console. This pull request makes this process smoother. I accomplish this with a slight modification to the enclose function (returning the selection)

From my perspective it would make sense to have something that allows that behaviour with other symbol like " — selecting the content, and returning before the first ".

Also, I wonder if we could pimp this with an

rstudioapi::showPrompt("Name", "What's the function name?")

So that the user is interactively asked for the function name, and it is pasted back in the document.

What do you folks think?

On another hand, it might be out of scope for {remedy} as the package is Rmd-focused 🤔

Yes, maybe this is beyond the focus of rmarkdown. It seems useful to allow this function with multiple different symbols. Besides ( and ", maybe also { as applicable in shiny development.

I really wish I could do this in the console, but can't see how.

This sounds analogous to rstudio 'extract function' and 'extract variable' shortcuts.

Thanks for the consideration.
