Transform duplicated short flag to upper case

[ntwcklng]

If you specify two options with the same first letter, the second one gets transformed to uppercase by default.

example.js:

#!/usr/bin/env node

const args = require('./')

args
  .option('debug', 'Run Debug mode')
  .option('deploy', 'Deploy')

const flags = args.parse(process.argv)

$ node example.js help:

  Usage: example.js [options] [command]
  
  Commands:
  
    help  Display help
  
  Options:
  
    -d, --debug    Run Debug mode
    -D, --deploy   Deploy
    -h, --help     Output usage information
    -v, --version  Output the version number

Note that the --deploy short-flag is now capitalized
