It works great, thank you. I had tried something on my own previously,
but without the ungreedy modifier and with replacements inside a
repeated while{} cycle instead of a callback. The main drawback in my
version was that an X near "hopefully" would have been replaced as
well (since technically it is between <b> and </b>). But that wasn't
what I wanted, of course.
