Open-in-browser results in 404 when target file not in root dir

[stoyandimov]

When opening a file in a browser from a repository sub-folder (CTRL-G CTRL-F and CTRL-O) the browser shows GitHub's 404 page because the file path is not included.

Expected:

• Navigate to a sub-folder inside the repo
• C-G C-F select a file
• C-O to open selected file in GitHub
• See the file in GitHub

Actual:

• Navigate to a sub-folder inside the repo
• C-G C-F select a file
• C-O to open selected file in GitHub
• See GitHub's 404 page
