New rustc output in tooltips shows path when it shouldn't

[estebank]

First of all, the new feature works great!

I believe that the second line in the output describing the full path isn't supposed to be there, as it is entirely redundant: the tooltip is being shown inline at the right span, the user doesn't need the span context. I wonder if it is because of an overly restrictive regex that didn't account for the leading whitespace?

Ah I think I messed up the regex?

.replace(/^ -->[^\n]+\n/m, "");

The whitespace should be variable length I suppose (I imagine it scales with line number width)
