I have been using the following pattern to allow a date in MM/DD/YYYY format to be broken after each solidus.
I never want extra space after the solidus; I want it to be translated into either a line break or nothing (the equivalent of "no-width optional break" as applied in MS Word, I believe). But does the TeX system allow additional space to be inserted? Should I be using a different pattern to allow for optional line breaks?
If I enter the date as
there are cases when its rendered form violates the margin.
