Coverage doesn’t seem to capture lines which are executed only during package precompile time and not while actually running the tests. Is there a way to also track coverage for these lines?

In [this example](https://codecov.io/gh/TotalVerb/EnglishText.jl/src/b8df1e5107772817b16319903ce0073f86f5c12d/src/articulate.jl), the `process` function is incorrectly marked as missed, despite having indeed run at precompile time.

I’ve found a workaround to this problem:

- Test on Travis/Appveyor with `--compilecache=no`; this runs the tests without precompilation so as to gather accurate coverage stats
- Then add an extra line `julia -e 'using Package'` to test the precompilation itself

See

for an example of a fix to this problem.
