Output of -h and --version goes to stderr instead of stdout

[samueloph]

Hello,

While working on the packaging of gpp for Debian I noticed that the outputs of -h, --help and --version goes to stderr instead of stdout, which can be a little bit confusing since it's not an error message.

This affected our testing infrastructure as it thinks that an invocation with -h had issues (it checks both for exit code and for stderr messages), this is something that we can easily workaround but I believe it would be nice if it could be addressed upstream.

Thanks,

Thank you for spotting this. I've committed a fix for this problem, which will take effect in the next release of GPP.
