Links with headers/anchors break

`home.md`
```md
# Root

[a link](file/somwhere.md)
```
`file/somwhere.md`
```md
# somewhere
- over the rainbow
# elsewhere
- idk
```
works nicely

but if you try this it doesn't...
`home.md`
```md
# Root

[a link](file/somwhere.md#elsewhere)
```
It tries to make a file named `somwhere.md#elsewhere` when clicked

Similarly, `[a link](#elsewhere)` tries to make a file called `#elsewhere`.

I am using this in the atom extension but I think it probably has to do with this project missing the feature.
