Ok, I'm on master now (e663cfec5a2dbf69d0f4360e1f8e05f81a037333).

With `line-spacing' of 50, it was always the previous line when clicking
in the two last thirds of the window (and the correct line in the 1st
third).  With `line-spacing' of 10, it were more lines too early
depending on how near the end of the window the click position was.

Yes, that seems to be it.  At least now with the current master HEAD,
point always jumps to exact the click position regardless of the
`line-spacing' value.
