tags with a comma separated list of values ...

[ghost]

ec2_tags.py - There doesn't seem to be a way to accommodate this ... we have some tags that are in the form "services:http,https,foo,bar" - I can't grain match unless I put that whole string in.

You should still be able to do glob matches, eg salt -G "ec2_tags:services:*https*" ...
