Spurious `DOCUMENTATION ERROR` when @docs on first line

[rtfeldman]

I should SSCCE this, but in the meantime: reporting it so I don't lose track of it.

Basic problem is that when elm-package checks for @docs it ignores them if they're on the first line.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

To restate the current behavior: the parser currently requires that @docs occur in the first column.

(FYI, the latest elm-format will reformat your example code to move the first @docs to its own line.)
