I do a fetch with a (Stash based) remote, and see a new remote branch, "origin/bugfix/XXX-999-pdf-to-tiff-quality"

I try "git checkout bugfix/XXX" then tab, nothing completes. I can see why, the branch is not local yet, but git itself would accept "git checkout bugfix/XXX-999-pdf-to-tiff-quality" , I get no completion because git treats branch names in special ways in some cases.

I hope I am just missing something, if not, I'll fork and fix if I can!
