[src/strtofr.c] parsed_string_to_mpfr: updated a FIXME comment.
In short, the current tstrtofr.c tests seem to always be hard-to-round
cases. The consequence is that some parts of the code are run, but not
completely tested, because for these cases, some intermediate results,
potentially incorrect, are thrown out due to the next Ziv iteration!
