This PR fixes two bugs when parsing unquoted multiline scalars:

Indented comment lines were incorrectly treated as empty strings, adding unwanted spaces to the final value.
Indented blank lines were incorrectly detected as having 0 indentation, causing the parser to stop early and throw aParseException.

For example, the following YAML would previously fail or parse incorrectly:

key:unquoted scalarnext line# this comment added an unwanted space (Bug 1)final line# The blank line above caused a ParseException (Bug 2)another_key:value
