Add ability to merge lines together

Ala markdown style:

paragraphify`
  This is a very long paragraph! So long I've decided to split it across
  multiple lines within the source code.

  That said I still do have other paragraphs in this call of paragraphify.
  I want to make sure these stay separate!

Perhaps best as a new NPM library; but that said, it does fit the purpose of "fixing whitespace".
