New port: textproc/markdownfmt: Tool for linting and formatting Markdown in-place (similar to gofmt)
markdownfmt is a linter similar to gofmt but for the Markdown language.
It is capable of autoformatting Markdown files in-place or generating diffs
with linting applied. Also, it is used in many plugins for formatting
Markdown files written for text editors like Vim or Emacs.
