Message sanitization should not always remove newlines

[giovannipapini]

Feature request

Removing message sanitization or at least set it optional.

Why?

It is a common standard putting a short commit message header followed by two newlines and a more descriptive message body. When I set the commit message length longer than 100 it is quite common that GPT generates a commit message with a header and a body but with this sanitization step newlines are removed and it messes up the result.
