GitLab CE doesn't support multiple assignees for issues.  
That's an enterprise feature.  See: https://docs.gitlab.com/ee/user/project/issues/multiple_assignees_for_issues.html

The feature to list commits from a subdirectory is already there but
so far the history link to it was missing. There is a History button
in the view_file.tmpl already so avoid showing two history buttons in
that case.

The GitHub webinterface has the same History button in the same place
so this makes gitea a little bit more compatible.

* Update http.go

As we've dropped support for go 1.8 (see 1.5.0 release post),
now we need to ensure that a minimum of go 1.9 builds correctly.

* Update "Upgrade from Gogs" en-us doc

- Move "Change gogs specific information" FROM/TO steps up
  to just beneath matching section header, adjust indention
  and explicitly specify syntax of code sample to provide
  highlighting

- Adjust header levels to match what appears to be the
  intended level, remove trailing decoration (see below)

- Move "Upgrading to most recent ..." section down, remove
  decoration (section header formatting likely covers this
  well enough already)

- Adjust indention and explicitly specify syntax of code
