prepare-Changelog tried to detect line endings based on the target file format, normally the ChangeLog file is in unix ('\n') line endings, and the perl script will prepare content with each line appended with a '\n', but when writing to the file, perl will try to convert line endings with the platform's native line endings and result in changing the whole file into dos format.
setting the binmode can fix this issue.
