- Get rid of this flood of warnings in Windows mingw build: warning: missing terminating " character The warning is due to the carriage return. When msysgit checks out files from the repo by default it converts the line endings to CRLF. Prior to this change when mkhelp.pl processed the MANUAL and curl.1 in CRLF format the trailing carriage returns caused unnecessary CR in the output.
