Configurable tab-size for project/repo UI
Depending on complexity and/or nesting level various projects need to have different tab sizes on file and diff pages.
I think it should not be constant (as described in #18893 (moved)) and repository level configuration would be just fine.
And (maybe) it is better to have it not 8-space size (standard value in most browsers) by default.
If you feel it like that, please consider upvoting the similar GitHub issue:
