The exclusions (--include/--exclude) for the recently introduced --all feature are applied to the executable script paths rather than the source script paths. So when working with compiled code the user needs to know the filepaths of the generated code. This is awkward for users of systems like ours that perform filepath mangling during compilation.

nyc used to have this behavior, but it was swapped via the awesome --exclude-after-remap feature that later became the default behavior via istanbuljs/nyc#1010. So in nyc now, exclusions are applied to the source script paths.

I'd like to propose that c8 should match the nyc behavior. As this would be a breaking change, I guess we should introduce it behind a similar opt-in flag (--exclude-after-remap).

If you are happy with the suggestion, I'll work with @j03m to prepare a PR tomorrow.

@bcoe I was thinking that here: https://github.com/bcoe/c8/blob/master/lib/report.js#L153 since we will already have the source map url in hand, the most simple approach would be to extract the source file and supply it to shouldInstrument instead of the executable file from the v8 json blob.

From there, I think the call to globSync for --all could then be simplified to supply the source file itself. This would in theory lose the fileio required to fake the sourcemap cache.

Any thoughts?

@j03m this approach sounds smart to me, but would we only get this optimization if we were to make --exclude-after-remap the default behavior?

@robpalme I think that this would be a good configuration option to add.

### BREAKING CHANGES

* Node.js' source-map and lineLength cache is now used to remap coverage output (this allows tools like ts-node to be supported, which transpile at runtime).
* temp directory now defaults to setting for report directory
* c8 will now load source-maps if possible and remap coverage accordingly
* switches to using NODE_V8_COVERAGE rather than inspector directly
* dropped subprocess support for the time being, while we march towards an initial implementation.
