Block styles with block chomping indicator (>-, |-, >+, |+)
You can control the handling of the final new line in the string, and any trailing blank lines (\n\n) by adding a block chomping indicator character:
, |: "clip": keep the line feed, remove the trailing blank lines. -, |-: "strip": remove the line feed, remove the trailing blank lines. +, |+: "keep": keep the line feed, keep trailing blank lines.
