options remain when reuse parse function

[taehyeong224]

var program = require('commander');
program
    .command('setup env')
    .option("-s, --setup_mode [mode]", "Which setup mode to use")
    .action((env, options) => {
        console.log("process.argv : ", process.argv)
        console.log("env : ", env)
        console.log("options : ", options.setup_mode)
        process.argv.splice(process.argv.length - 2, 2)
        program.parse(process.argv);
    });

program.parse(process.argv);

$node test.js setup env -s s

output

process.argv :  [ '/usr/local/bin/node',
  'path/test.js',
  'setup',
  'env',
  '-s',
  's' ]
env :  env
options :  s
process.argv :  [ '/usr/local/bin/node',
  'path/test.js',
  'setup',
  'env' ]
env :  env
options :  s

I changed 'process.argv' for some test, and I found options remain .

I expected options.setup_mode was undefined. but -s options not undefined.

If you want to call parse multiple times, the best option is to create a fresh Command object.

See #438 for discussion and examples.
