The following works in MkIV but fails in MkIV:
\unprotect
\def\!!yesandon{yes,on}
\doifinsetelse{yes}\!!yesandon
\ExpandSecondAfter\doifinsetelse{yes}\!!yesandon
It’s awkward but this how it works in MkII.
\ExpandSecondAfter is MkII only, so I cannot use it for code that is to be
used in both MkII and MkIV. So, I re-request my original proposal:
in core-gen.mkii
\def\p!doifinsetelse#1#2#3#4%
{\donefalse
\edef\!!stringa{#3}%
\ifx\!!stringa\empty
\else
- \processcommalist[#4]\p!docheckiteminset
+ \processcommacommand[#4]\p!docheckiteminset
\fi
\ifdone\expandafter#1\else\expandafter#2\fi}
