This short patch series adds support for a new `--count` argument for limiting the output of `show-ref` (à-la the `for-each-ref` option by the same name). This is useful in contexts where a caller wants to avoid enumerating more references than necessary (e.g., they only care whether a tag exists, but not how many or what they are called) but doesn't have control of the output stream (e.g., they are in Ruby and can't pipe the output to `head -n 1`). The first patch is preparatory, and the second patch implements the new option. This series doesn't conflict with my recent [1], and can be applied independently. Thanks in advance for your review!
