Feature request: replace "-w" CLI option to be "--watch" shorthand

[trevordmiller]

Many CLIs use -w as a shorthand for --watch. Currently, the Jest CLI doesn't have a shorthand for --watch; it would be nice if -w could become the --watch shorthand, and the current -w (shorthand for --maxWorkers) could change to -m.

I like this idea, -w feels natural for watch mode... Breaking change, but really interesting

I don't think it's necessary to break this. How about mapping "yarn w" to "jest --watch" in the scripts section?

It's not about an individual project, but CLI use in general. -w for watch seems to be a standard:

• babel: https://babeljs.io/docs/usage/cli/
  

• webpack: https://webpack.js.org/api/cli/
  

• Post CSS: https://www.npmjs.com/package/postcss-cli
  

• Mocha: https://mochajs.org/
  

• AVA: https://github.com/avajs/ava
  

etc.

They do, and maybe jest should have, but it's a pretty trivial reason for a breaking change.

No worries, just thought I'd suggest it :) Thanks for all the great work with Jest.
