[dev-context] Reversed alignment for left and right

[Wolfgang Schuster]

Hi Hans,

while for backwards compatibility you won’t change \setupalign[leftt|right] the current implementation makes it possible to change the behavior with a simple change in the code.

\newconstant\c_spec_align_state_method

%\setvalue{\??aligncommand\v!right          }{\c_spac_align_state_horizontal\plustwo  }
%setvalue{\??aligncommand\v!left           }{\c_spac_align_state_horizontal\plusthree}
\setvalue{\??aligncommand\v!right          }{\c_spac_align_state_horizontal\ifcase\c_spec_align_state_method\plustwo\else\plusthree\fi}
\setvalue{\??aligncommand\v!left           }{\c_spac_align_state_horizontal\ifcase\c_spec_align_state_method\plusthree\else\plustwo\fi}

\unexpanded\def\enablereversealignment{\c_spec_align_state_method\plusone}
