--stdin causing a TypeError to be thrown with Node v6 #504
Description
I first noticed this after my linting stopped working in SublimeText using SublimeLinter after installing Node v6. It seems to be related to this change nodejs/node#5348
The error can be seen in the Sublime console (with SublimeLinter in debug mode) or at the shell by:
$ cat test.js | standard.cmd --stdin --verbose
standard: Unexpected linter output:
TypeError: Path must be a string. Received undefined
