[latex3-commits] [l3svn] 02/02: Corrected the definition of 'explicit space' by deleting the requirement that it has character code 32.

[Bruno Le Floch]

I really don't have time to do extensive tests, but that sounds wrong.

\lccode32=`*
\def\grabnshow#1{\showtokens{|#1|}}
\lowercase\expandafter{\expandafter\grabnshow\space\relax}
\uppercase\expandafter{\expandafter\grabnshow\space\relax}
\bye

shows |*| then |\relax|, indicating that charcode=32 is important.
