Wrong.  Consider the following eqn definitions:

define alpha	% "\S'+15'\s-1\H'+1'\(*a\H'0'\s+1\S'0'\h'0.2n'" %
define beta	% "\S'+15'\s-1\H'+1'\(*b\H'0'\s+1\S'0'\h'0.2n'" %
define gamma	% "\S'+15'\s-1\H'+1'\(*g\H'0'\s+1\S'0'\h'0.4n'" %
define delta	% "\S'+15'\s-1\H'+1'\(*d\H'0'\s+1\S'0'\h'0.3n'" %

Within eqn delimiters, alpha will be printed at an oblique angle of 15
degrees.  The other operations alter the aspect ratio (for aesthetic
reasons) and add a slight space at the right of the character.
