Emacs doesn't insert any gaps, it just computes the line metrics from all the characters displayed on that line. I've read the discussions of the FreeType developers, but couldn't understand what they were talking about, as the discussion was in terms of internals of FreeType, and I don't know enough to map that to what the Emacs display engine does. My point is that this seems to have nothing to do with the FreeType library or its version, since I see the same on a system that uses neither FreeType nor this particular font. IOW, this looks to me "normal", i.e. Emacs always worked like that.
