This serves as a alternative to the code-review package. I'm adding it

forge-post-mode uses temporary files for editing, which means that
prettier can't determine the formatter to use based on the
filename. Hence we need to explicitly pass `--parser markdown` as a CLI
arg to prettier.
Latest master build of magit seems to have issues with the status
buffer, where it turns on syntax high-lighting for quoted strings and
other weirdness that leaks all over the status buffer.
