Are we sure the bisected change (dae3c4e89b27) itself doesn't need a 
tweak? From all the explanations here, I would expect

  (set-face-attribute 'default nil :height 110 :weight 'medium :family 
"Inconsolata")

to work correctly even without your "kludge". But it does not.

Like, okay, Inconsolata_dz has a weird "style" ("dz"), but the plain 
Inconsolata is "Medium".

Since I'm measuring window height in characters (rows) here and not in 
pixels, I don't think even the first change should happen.

Though of course the window size in pixels should change.
