[Pharo-dev] patching vmmaker

Hi, While building the VM from generator.image through eval handler, I noticed spurious blank lines in the log output. I created a changeset that removes these and creates a compact log (all in VMMaker package). My generator.image only throws up local repos for MC. smalltalkhub.com seems to be down. How do I upload the patch to VMMaker mainline? Regards .. Subbu
