Line 16 does a similar check, maybe we could add the if condition there with an && instead of opening a new one? 

Also: This would only work if in this case:

```
# github.com/VividCortex/ewma v1.0
```

but not in this one:

```
#github.com/VividCortex/ewma v1.0
```

Since $package is "#github.com/VividCortex/ewma". Maybe a regexp matching /^#/ would do the trick? This wouldn't support comments like this one

```
github.com/VividCortex/ewma  v1.0    #This is a comment
```

But it would define comments as "whatever that has a '#' at the beginning of the line", which is probably good enough.
