          Yield matching requirement strings.
  
          The strings are presented in the format demanded by
          pip._vendor.distlib.util.parse_requirement. Hopefully
          I'll be able to figure out a better way to handle this
          in the future. Perhaps figure out how pip does it's
          version satisfaction tests and see if it is offloadable?
  
          FYI there should only really be ONE matching requirement
          string, but I want to be able to process additional ones
          in case a certain package does something funky and splits
          up the requirements over multiple entries.
