This makes a minor refactor to main to avoid use of a global exit code variable.
Instead, we declare a mainCmd struct that stores global program state like exitCode.
This also allows us to change the definition of stdin, stdout, and stderr, so that tests can provide varying values.
This contains no logic changes. All changes are mechanical. Roughly:
report(error)
report
flag.Parse()
os.Args
flag.CommandLine.Parse
exitCode
