Wrong link generation of some URLs

[andreynering]

• Gitea version (or commit ref): Current master: f1d2f16
• Git version: Not relevant
• Operating system: Not relevant
• Can you reproduce the bug at https://try.gitea.io:
  • Yes (provide example URL)
  • No
  • Not relevant

Description

Take as example these links:

https://foo.bar.com/post/2017/03/16

https://foo.bar.com/post/2017/03/16/index.html

https://foo.bar.com/post/2017.03.16

They're not Gitea/GitHub issues, but Gitea thinks it is. Screenshot:

There's also the slight annoyance where just typing #1337 becomes a broken link since it's not a valid issue/PR-number 😅
