turtle-1.3.3

• Bug fix: Change textToLines to behave like Data.Text.splitOn "\n"
  instead of Data.Text.unlines
  • This fixes weird behavior around handling empty strings. splitOn does
    the right thing, but unlines does not. For example, this indirectly
    fixes a regression in sed, which would discard empty lines
• Bug fix: which/whichAll now behave correctly on Windows
• Add new cptree/single utilities
• Documentation fixes
