Well, I talked a bit with Huw about this so apologies to him if I mangled
what he said, but ... it seems that the functions we use to get the size
of the screen don't always return correct values. I don't know why.

If you mean via DDC then I guess this should work in most places, but for
whatever reason it does not work here :( In particular, xdpyinfo says:

screen #0:
  dimensions:    1024x768 pixels (321x241 millimeters)
  resolution:    81x81 dots per inch

So it appears to know the screen size (I measured with a ruler and
321x241 is right), but it gets the DPI too small anyway. At 81 dpi the
text is hardly readable.

Yep, this only affects the default when nothing is specified in the config
file (in fact in the default config file this was always specified anyway
so this is just restoring the old behaviour in the absence of he config
file really).
