Error when a box has options

[jkuczm]

Bug reported by Matthew Galles.

When "formatting" boxes, like SuperscriptBox, have options, their conversion to TeX results in errors.

Minimal example is:

CellToTeX[SuperscriptBox["T", "1", MultilineFunction -> None], "Style" -> "Input"]
(* CellsToTeXException::unsupported: Box: MultilineFunction->None is not one of ...*)
(* Failure[...] *)

Quick workaround is to remove options from affected boxes before conversion to TeX.
For example:

CellToTeX[something /. SuperscriptBox[x_, y_, ___] :> SuperscriptBox[x, y], ...]
