MacVim registers the mvim url handler to open files and directly jump to lines and columns.
We can use this to convert stacktraces reported by RSpec into clickable mvim-links.
Requires at least MacVim 7.3. To change how MacVim opens external files go to
'Preferences' > 'Open files from applications' and select 'in the current window' and from
the dropdown menu select 'and set the arglist' to open the file in the last active buffer.
Cmd-Click on an mvim-link to open the file.

I developed iTerm2's Semantic History feature for this very purpose. http://vimeo.com/21872771
You can Cmd+Click any path with or without a line number and it will open it in your text editor of choice.
Configure it by going to Preferences -> Profiles -> Advanced -> Semantic History.
