Luckily this can be made less convoluted:)

Should parentheses be recognized? e.g. A₍₁₎ (A_{(1)}) is sometimes
used to denote e.g. a submatrix of A corresponding to the removal of
column 1 in A. Personally, I would mostly always wrap such stuff into
math anyway (entities being the exception), since I want it in
math-mode anyway.
