The above example was the wrong one, sorry.  What I actually wanted to
show are inconsistencies.  In the same section you can find

```
c''4-3 e-5 b-2 a-1
```

which Pygments translates to

```
@t{c''} @t{4} @t{-3} @t{e} @t{-5} @t{b} @t{-2} @t{a} @t{-1}
```

that is, the `-` is not typeset in bold.  The next one

```
c''4-ˆ c-+ c-- c-!
```

gets translated to

```
@t{c''} @t{4} @tb{-^} @t{c} @tb{-+} @t{c} @t{--} @t{c} @tb{-!}
                                          ^^^^^^
```

showing bold and non-bold for `-` in the same function.
