Linkify terminal paths without any path separators #22772
Description
Currently we're limited to the current workspace (knowledge of shell's cwd is blocked on #20676), but it would be good to linkify files in the current directory that don't have path separators. This would linkify the files in ls for example:
❯ ls
build node_modules scripts appveyor.yml issue_template.md npm-shrinkwrap.json product.json tsfmt.json
extensions out src CONTRIBUTING.md jsconfig.json OSSREADME.json README.md tslint.json
i18n resources test gulpfile.js LICENSE.txt package.json ThirdPartyNotices.txt
