<pre>Consider:
```
#line 42 "other.cpp"
int main() { return 0; }
```
The report currently looks like:
```
foo.c:
| 1|#line 42 "other.cpp"
1| 2|int main() { return 0; }
```
Use a sub-view to display the current filename and line number. On the clang
side, we need to include the right information from the #line directive in the
coverage mapping. Then we need to teach llvm-cov to display the sub-view.</pre>
