commit f284b58838537ae635814999b465b71b7831f8c5
Author: Jean-Marc Lasgouttes <[email protected]>

Output superscripts before subscripts
This is useful when using primes. Indeed, in math mode, `'` is
transformed by LaTeX to `^{\prime}` and merged with the next
superscript if there is one.
Therefore `$x'^2_3$` compiles whereas the original output `$x'_3^2$`
did not.
Fixes bug #13004.
