Coalesce quotes with shellcheck -p diff

[Ericson2314]

For new checks and feature suggestions

Here's a snippet or screenshot that shows the problem:

My understanding from NixOS/nix#10857 is that shellcheck -p diff suggests things like

foo$bar#baz$quux

=>

foo"$bar"#baz"$quux"

Here's what I wanted or expected to see:

It would be nice if we could instead coalesce the quote so we we have

foo$bar#baz$quuex

=>

"foo$bar#baz$quux"

is there a mode to do that? Would it be hard to add? Is it easy to fake the feature with a regex in the meantime? :D
