fix Patch file parse error in windows

[bill2004158]

fix new line for windows.

[bill2004158]

in windows, the line break is "\r\n". (while it is "\n" in Linux/Unix).
so after split by "\n",
then first char of blank line will be "\r" for window.

so "Treat blank lines as context" should include "\r".

Error fixed in windows

I'm using Windows and VS Code and I just changed the end of line sequence to be LF instead of CRLF in the patch file and the problem solved.
