From: Jacob Keller <jacob.keller@xxxxxxxxx>
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.
