call RangeJsBeautify() insert new line when .editorconfig: insert_final_newline=true

[sabakugaara]

if .editorconfig insert_final_newline=true, call RangeJsBeautify() will insert a new line after vim selected range

@sabakugaara thx

Maybe a way to override the global jsbeautify setting while calling the RangeJsBeautify function to solve this?

@nerdpad I think we cuold delete(or rewrite on false) insert_final_newline if end of the range does not equal last line
