In Lean syntax declarations the following pattern is quite common:
|
||
```
|
||
syntax term " + " term : term
|
||
```
|
||
that is, we place spaces around the operator in the middle. When the
|
||
`InfoTree` framework provides us with information about what source token
|
||
corresponds to which identifier it will thus say that `" + "` corresponds to
|
||
`HAdd.hadd`. This is however not the way we want this to be linked, in the HTML
|
||
only `+` should be linked, taking care of this is what this function is
|
||
responsible for.
