 The encoding in the source mapping for the bytecode is more complicated:
 It is a list of ``s:l:f:j`` separated by ``;``. Each of these
 elements corresponds to an instruction, i.e. you cannot use the byte offset
-but have to use the instruction offset or PC (program counter).
+but have to use the instruction offset (push instructions are longer than a single byte).
 The fields ``s``, ``l`` and ``f`` are as above and ``j`` can be either
 ``i``, ``o`` or ``-`` signifying whether a jump instruction goes into a
 function, returns from a function or is a regular jump as part of e.g. a loop.
