Rain fmt handles windows linebreak CR LF differently with unix linebreak LF

[jerry118118]

Rain fmt will separate multi line comments with windows return CR LF with new lines.

For example, if the comment lines below are separated by windows linebreak CR LF,

AWSTemplateFormatVersion: 2010-09-09

# Comment line 1
# Comment line 2
# Comment line 3

Description: Hello World

after running rain fmt, it will generate new lines between my comment.

AWSTemplateFormatVersion: "2010-09-09"

# Comment line 1


# Comment line 2


# Comment line 3
Description: Hello World

But if the comment lines are separated by unix linebreak LF, it will not add new lines into my comments.

AWSTemplateFormatVersion: "2010-09-09"

# Comment line 1
# Comment line 2
# Comment line 3
Description: Hello World

Is that expected behavior? As I am developing cloudformation template mostly through windows, and most of my files are created using windows. Rain fmt will break all my multi line comments :(
