More informative syntax errors

[toji]

Currently if a required script has a syntax error you will receive a only slightly helpful message along the lines of:

Uncaught SyntaxError: Unexpected token , in http://localhost:8000/your-huge-script.js

This usually includes a link to the throw statement in require.js makeRequire. Unfortunately that's simply not enough information to effectively locate and fix the syntax error, which means you spend a lot of time scanning through the file line by line for errant commas or periods.

If there's any way to include a line number or at least some surrounding code in this error message it would be greatly appreciated!

I could extract the JSHint middleware from Montage and set it up to work with stand-alone Mr. Otherwise, to combat this problem, I’ve just been using node my-huge-script.js to get a precise error.

That's what I've been doing too, but it's not a terribly elegant solution. A JSHint pass on failure would be nice!

Looking for a chore, @Stuk?

Will take a look.
