Vim jump to a file using ctr-w gF with a @ in the path like dirwith@funnyname/path:34

My stack trace errors in ruby on rails look like below. I have happily used ctr-w gF to jump to the file and go to the line number following the file for a while.

However I started using RVM and gem_sets, and this puts a @ symbol in the dir which apparently confuses Vim. How can I use my beloved ctr-w gF while this is the case?

Include the @ character in 'isfname'.

:set isf+=@-@

For more information:

:h 'isfname'
