That is not completely correct because for "\alpha-\beta", only \beta is
prettified.
However, \alpha, \alpha. \alpha() \alpha[] work well with \alpha being
prettifyied
even though the next character is a comma, period and parenthesis.
To cater for prettifying tex, we could have another function where one can
construct
the prettify.
