Description

The breadcrumb links on the edit file view are invalid. See the example below.

Example:

   Link Text: TestRepo                                       / Folder1                                               / Folder2
    Link URL: http://localhost/geek1011/TestRepo/src/master    http://localhost/geek1011/TestRepo/src/master/Folder1   http://localhost/geek1011/TestRepo/src/master/Folder2
Expected URL: http://localhost/geek1011/TestRepo/src/master    http://localhost/geek1011/TestRepo/src/master/Folder1   http://localhost/geek1011/TestRepo/src/master/Folder1/Folder2

This does not happen when you put a slash in the textbox, it is only on the initial render of the page.

I posted the same issue on Gogs a while ago and Unknwon fixed it with this commit.

Looking forward for this fix in Gitea too.
