Incorrect warning "yyextra->inside" instead of "inside"

We get warnings like:
```
warning: reached end of file while yyextra->inside a 'code' block!

warning: Ignoring \brief command yyextra->inside argument documentation
```
this is due to the fact that the scanner has been made reentrant (inside becomes yyextra->inside and this slipped into the warning strings as well)
