Thanks for the re-roll.
In the previous iteration, I wasn't sure this was the right approach
because I thought it would be better to pass RUN_SETUP and let
run_builtin_command() take care of the prefix-setting. Unfortunately,
as 5410a02 (git-rev-parse --parseopt, 2007-11-06) indicates, we have
to run setup_git_directory() in cmd_rev_parse() after parsing
--parseopt, as 'git rev-parse --parseopt' can be run outside a git
repository. You might want to include this note in your commit
message for the benefit of other readers.
Other than that, I just have one small suggestion: it's possible to
avoid passing output_prefix around, and simplify show_file() a bit if
we acknowledge that printing "--" is not the same as printing a file
(although the condition is the same). Would you like to squash this
in?
