Deep linking into a range of lines of source

I'd like to be able to link to a source view and have a range of line numbers highlighted on the left (e.g. lines 1–10; I wanted to draw someone's attention to a block of CSS rules).

I tried the following approaches on stash-dev, but neither worked:

1. clicking and dragging on the line numbers, and
2. clicking on the first line number and shift-clicking on the second.
