interpret -- as stdin

[neonstalwart]

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.

@neonstalwart Do you mean to modify shjs to allow the equivalent of this?

$ echo 'echo foo' | bash

If so, I think this will work as required:

$ echo "require('shelljs/global'); echo('foo');" | node

I'm closing this, since this seems to solve the issue. If this isn't sufficient, let me know, and we can reopen.

I'm not sure if it's equivalent to what I meant but I've moved on quite a
lot since the time I opened this and no longer care.
