ignoreWhitespaceOnlyLines could be on by default for YAML

[clonedagain]

In YAML, multiline strings are represented by | followed by the string, indented one level to the left.
Thus, empty lines are represented as all-space lines.

Could you please enable ignoreWhitespaceOnlyLines for YAML by default ?

Example :

Hello

World

is represented as :

|
  Hello
  <- notice the spaces here.
  World
