Consistent Function Label Naming for Sections

[Benio101]

Make [print.fun] consistent with other label names.

If I should make a P version of paper instead of github PR, please, let me know.

Label naming is entirely editorial, although we tend to avoid changing label names without consulting with CWG or LWG. Please don't spend paper numbers on such matters unless directed to do so by the Project Editor. You can easily present the consistency argument in the pull request description inline instead of requiring me to click on a PDF link.

@jwakely , any concerns about the label rename here?

(And now that you've invested in a paper number, do make sure it appears as a P paper in the next mailing; allocating paper numbers without publishing the corresponding paper isn't helpful either.)

Please add a \movedxref to xrefdelta.tex:
