Beware: the 'bold' face changes the metrics of the font glyphs (wrt

Only non-monospaced font, though, right? Or ones without a 'bold' variant.
No, not only those. I'm talking about the_vertical_ metrics, so
whether the font is monospaced is not relevant. Try marking files for
deletion in Dired, and you will see that, at least with some fonts and
some sizes. Here on MS-Windows the default face's font (Courier New)
does that, for some sizes of the font. I have customized
eldoc-highlight-function-argument to use 'underline' instead of 'bold'
for that very reason.
