As things stand, this is currently more correct: the pre_user_display_name
filter is called before the corresponding pre_user_first_name and
pre_user_last_name filters. So any changes the latter two filters make will
not be reflected in the display name.

I think the correct solution would be to simply move the construction and
filtering of display_name to after the all the other name parts in core.
That way the existing filters are enough to make the change. Optionally, a
default filter could be put in place to change the current behaviour.
