Expected

dedent("\\nu") should return the string unchanged.

Actual

dedent("\\nu") turns the \\n into a newline, i.e. returns a newline character + u.

Additional Info

This happens because result.replace(/\\n/g, "\n") is called regardless of the value of escapeSpecialCharacters, i.e. regardless of whether dedent is called as a tag on a template or as a function on a string.
An easy fix would be to make the replacement conditional, solving this particular problem. (However, it would still not work for dedent`\\nu` because here, still the \\n would be replaced 🤷‍♂️)
