             Bug #: 38099
           Summary: in Gerrit make tab size 4 instead of 8

I fully understand that this may be a bikeshed, but I'll try anyway.

The diff view in Gerrit shows indentation tabs of 8 spaces. When showing two
compared revisions of the file, it makes the display very wide. On small
screens this very often requires horizontal scrolling.

I am not making any assumptions about the most common tab size among Wikimedia
developers. I'm just thinking of being practical and helping people with
smaller screen to do code review more efficiently.

If it's possible, it would be helpful to define the Gerrit tab size for 4
