* Allow `--write` to be used with `--list-different`
This makes it possible to simultaneously check for formatting errors and
fix them, which can be useful for CI services. For example, a CI service
could run:
prettier --list-different --write $FILES || git diff --exit-code
to show the formatting errors. Before this change, it would be necessary
to do:
prettier --list-different $FILES || (prettier --write $FILES; git diff --exit-code)
Here are some commands which are useful to verify that the outputs and
exit codes of `prettier --list-different` and `prettier --write` have
not changed:
./bin/prettier.js --list-different index.js src/*.js bin/*.js; echo $?
./bin/prettier.js --write index.js src/*.js bin/*.js; echo $?
* fixup! Allow `--write` to be used with `--list-different`
