This is a minor bug I noticed when working on Windows;
caddy fmt
always outputs unix line endings (LF), so if a Caddyfile crafted on Windows with CRLF line endings, theinput is not formatted with 'caddy fmt'
warning would always appear.This change normalizes the input Caddyfile to LF line endings to avoid this problem when comparing.
