Read merged coverage as CLI text output

[wyqydsyq]

I'm currently using the nyc merge command to merge the coverage of my unit tests and integration tests which run separately, the resulting JSON and HTML report files are correctly merged, but I would also like to get the text summary of the merged results displayed on the CLI

There needs to be an option on the merge command to tell nyc to also display the text report of the merged results

The way I've been solving this is actually to not use the nyc merge command and instead run sequential test runs with the --no-clean flag. When you run nyc report at the end of all that, you get a nice, combined html report with all the runs together. Example:

package.json scripts:

    "cover": "npm run cover:unit && npm run cover:integration && npm run cover:report",
    "cover:unit": "nyc --silent mocha",
    "cover:integration": "nyc --silent --no-clean mocha \"test-integration/**/*.ts\"",
    "cover:report": "nyc report --reporter=lcov --reporter=html --reporter=text",

The first unit test run doesn't have the --no-clean flag. So it wipes the .nyc_output directory before starting. The integration test has the flag and just appends to the folder. The report then combines all of it.

#1093 put @janiukjf's suggestion on the readme so I'm closing this for now.
