After some tracing and hard thinking Taco and I found interesting spaces
showing up in the output that result from a kludge in tikz:
Normally one will use \ignorespaces to catch spurious spaces but tikz
invokes \nullfont assuming that its fontdimen 2 is zero. But, in context it
no longer is (prelude to delayed font loading).
You can put this in cont-new.mkiv as a temporary hack
\let\normalnullfont\nullfont
\def\nullfont
{\fontdimen1\normalnullfont\zeropoint
\fontdimen2\normalnullfont\zeropoint
\fontdimen3\normalnullfont\zeropoint
\fontdimen4\normalnullfont\zeropoint
\fontdimen5\normalnullfont\zeropoint
\fontdimen6\normalnullfont\zeropoint
\fontdimen7\normalnullfont\zeropoint
\normalnullfont}
Perhaps this should be forwared to Christian Feuersaenger. He is very open
to bug reports and will probably be willing to fix it in some way in TikZ.
feel free to do so; probably something like this is needed:
\def\pushnullfont
{\edef\popnullfont
{\fontdimen2\nullfont\the\fontdimen2\nullfont
\fontdimen3\nullfont\the\fontdimen3\nullfont
\fontdimen4\nullfont\the\fontdimen4\nullfont}%
\fontdimen2\nullfont 0pt\relax
\fontdimen3\nullfont 0pt\relax
\fontdimen4\nullfont 0pt\relax}
\pushnullfont
....
\popnullfont
as fontdimens are assigned global.
