/**
* Will attempt to parse the rest of the input line according to the
* restrictions given by the format string. The format string is used to
* specify, in the given order, how to parse the next token. The following
* format is accepted (strictly):
*
* s -> Source register
* d -> Destination register
* l -> Label
* c -> Constant
* n -> Literal number
* t -> Place an empty term after this term
* [ -> Start 'or' expression (non-recursive)
* ] -> End 'or' expression
*
* Note that the or expression works as expected, so "[lcn]" translates to
* "take whichever successfully parses first, either a label, constant, or
* a number".
*
* If the or condition fails, or any parsing fails, an error is printed
* and all processing stops (the function does however return instead of
* calling exit()).
*
* @param prog Contains general program information thus far gathered,
* and is used for handling error reporting.
* @param opcode The binary operation that this line started with.
* @param fmt The format string for what arguments to expect.
* @param misc Any bits that need to be added as the last child to the
* opcode term.
