Steps to reproduce:
1. Create otherwise valid yaml file, but instead of spaces use tabs.
2. See error when loading with require:
YAMLException: JS-YAML: the stream contains non-printable characters in "/home/developer/code/request-tester/app.yml" at line 1, column 1
What should appear:
1. Either error at appearance of first invalid character (tab)
2. or general error that there are tabs in the file
I should have some time this weekend to do the pull request here.
Correct the non-printable regexp. Closes #64
Just a typo. Thanks for the report!
