this boils down to:
\unexpanded\def\textormathglue#1#2#3%
{\begingroup
\scratchdimen=#1\hspaceamount\empty{#3}%
\scratchskip=\zeropoint
\!!plus.5\scratchdimen
\!!minus.3\scratchdimen\relax
\ifmmode
\mskip#1#2%
\else
\kern\scratchdimen
\hskip\scratchskip
\fi
\endgroup}
\def\thinglue {\textormathglue+\thinmuskip 1}
\def\medglue {\textormathglue+\medmuskip 2}
\def\thickglue{\textormathglue+\thickmuskip3}
why the kern followed by the skip? why not just
\unexpanded\def\textormathglue#1#2#3%
{\ifmmode
\mskip#1#2\relax
\else
\begingroup
\scratchdimen#1\hspaceamount\empty{#3}%
\scratchskip
\scratchdimen
\!!plus .5\scratchdimen
\!!minus.3\scratchdimen
\hskip\scratchskip
\endgroup
\fi}
