You can also get "step down" ferrules that allow you to use an end cap on 5mm housing, yet allow it to seat properly in an old style cable-stop that is really meant to accept a "naked" housing of 4mm diameter.
I used one of these when I converted my old Peugeot to (gasp)

By the way, I bought mine from a local bicycle shop. I didn't
actually have to special order one.
