Expand skipped paths.

[mtth]

Path keys corresponding to skipped paths (where the value is false)
did not get expanded, so only module IDs were supported. This lets us
skip relative paths as well.

follow existing code style and spacing

My bad, updated the indent width. There aren't any other else statements in the code, so I indented it like your catch statements. Let me know if this isn't what you had in mind.

Just to make sure I understand this change. Previously a browser field value of:

browser: {
    "./local-file.js": false
}

Would not work when required from another module (require(foo/local-file)) because the path would not be expanded? And this PR fixes that behavior?

This is for requires inside the same package. Assuming the following folder structure (a bit contrived for simplicity):

• index.js (with require('./lib/hide'))
• lib/
  • index.js (with require('./hide'))
  • hide.js (should be always skipped for browser builds)

In this case, we have to set both ./hide and ./lib/hide to false in package.json (which wouldn't be the case if they were just relocated):

browser: {
    "./hide": false,
    "./lib/hide": false
}

With this change, skipped keys behave the same as relocated ones. Hope this makes sense.

Makes perfect sense. Great fix!
