Sure it needs to be fixed, but isn't there an extra left parenthesis
after ci_rank?

Yes!! I find it annoying too. The trouble is, telling the two uses of "'"
apart isn't exactly trivial: you need to parse the source to see if the
preceeding expression can be legitimately interpreted as a matrix. Not
easy.

Maybe it can be pseudo-fixed via the following hack: colour-code as
string only if you have 2 "'"s in a line (but then, it's quite possible
you have two transpositions in the same line; it just "fixes" the case
when you've only got one).
