How to escape colon in YAML?

This is a bug/feature about YAML parser.

If you want to add something like echo "baseurl: blog/" >> _config.yml, this won't work because colon will be parsed into =>. Even adding quotes around it fails.

To do it, we can split it into two lines.

printf "baseurl:" >> _config.yml
