easier way to specify alternate reporter

Would it be possible to change the --reporter command-line option so only a name can be specified to use built-in reporters rather than the full path to them?

For example, I'd like to use
--reporter=tap
instead of
--reporter=/usr/local/lib/node_modules/nodeunit/lib/reporters/tap.js

Start by locating the command-line handling for the --reporter option and the built-in reporter files, including tap.js. Check how the current full-path value is resolved and any existing CLI tests. Done means --reporter=tap selects the built-in TAP reporter while existing full-path usage continues to work.
