Jekyll doctor doesn't find conflicting redirects

[szarnyasg]

Jekyll doctor is supposed to detect conflicting redirects such as this:

git checkout bb0e56854c5d45ac9701141321f32dc8e6940179
head -n 5 docs/archive/0.10/internals/storage.md docs/internals/storage.md

==> docs/archive/0.10/internals/storage.md <==
---
layout: docu
redirect_from:
- /internals/storage
title: Storage

==> docs/internals/storage.md <==
---
layout: docu
title: Storage
redirect_from:
   - /internals/storage

However, it doesn't find this conflict:

bundler exec jekyll doctor

  Your test results are in. Everything looks fine
