FWIW, as a user I consider adding bold and/or italic properties a more
subtle change than changing the color, even though as a developer I
know that they're implemented as separate fonts.  (Which is why I have
the magit-item-highlight face customized to bold+italic, and therefore
noticed when adding it as a mouse-face to a section didn't have the
same effect as highlighting the section by moving the point into it.)
