To check what was going on, I loaded LucidaBrightOT.otf into FontForge,
and I saw the too small bounding box there (actually a negative ‘side
bearing’).  So I think that OpenType fonts contain the boundary box data
as well.  We certainly cannot blame luatex or xetex.

As nobody else complained about this, I suspect this is a new issue,
maybe related to this sentence that appears in the NEWS.txt for version
1.800:


  Glyphs that appear in both math and text fonts are the same.


If someone has the same issue: I currently work around it by corrective
kerning, applied through a FeatureFile (which is a luatex-only feature
available through the fontspec package):

  pos \plus \zero 259;

and similar for other glyphs that appear after plus in the text.
