in jshint/jshint#687, there's an interest in being able to use the jshint cli interface by passing -- as a filename and having the input from stdin used as the contents of the file. since jshint uses shelljs i was wondering if it would be possible to add this support to shelljs - it's probably useful to lots of other people who use shelljs too.

i'm not very familiar with shelljs but if someone could give me some guidance on how to approach this, i might take a stab at it.
