From: Jacob Keller <jacob.keller@gmail.com>
Teach git name-rev to take a string list of patterns from --refs instead of only a single pattern. The list of patterns will be matched inclusively, such that a ref only needs to match one pattern to be included. If a ref will only be excluded if it does not match any of the patterns.
Add tests and documentation for this change. The tests do use dynamically generated output as part of the expected output because the expected output is the raw commit-id and it seemed like a bad idea to hardcode that into a tests expected output.
