Teach git name-rev to take multiple --refs stored as a string list of patterns. The list of patterns will be matched inclusively, and each ref only needs to match one pattern to be included. A ref will only be excluded if it does not match any of the given patterns. Additionally, if any of the patterns would allow abbreviation, then we will abbreviate the ref, even if another pattern is more strict and would not have allowed abbreviation on its own. Add tests and documentation for this change. The tests expected output is dynamically generated. This is in order to avoid hard-coding a commit object name in the test results (as the expected output is to simply leave the commit object unnamed).
