[dev-context] math-stc.mkvi: \mathdouble

Hi Hans, the definition for \mathdouble is wrong (I guess you did this because it’s not really used) because it takes only a code point instead of two (the second always takes the default value 0): \unexpanded\def\mathdouble{\begingroup\dodoubleempty\math_stackers_handle_double} \def\math_stackers_handle_double[#category]% {\math_stackers_direct_double\plusone\plusone {\iffirstargument#category\else\v!bottom\fi}} % will be defined later on \def\math_stackers_direct_double#top#bottom#category#codepoint#text% {\math_stackers_make_double#top#bottom{#category}{#codepoint}{0}{#text}% \endgroup} Wolfgang
