Diff elides single lines
Summary
When rendering diff hunks, GitLab can elide a single line.
Steps to reproduce
Get a diff which has 1 line between the diff hunks. View the diff in GitLab.
Example Project
It isn't here, but it is on our instance. Seejthis MR diff where line 42 is replaced with a elision render.
What is the current bug behavior?
Elision can hide a single line with another line.
What is the expected correct behavior?
GitLab is rendering a line anyways. Just show the line instead of eliding it.
