From 93ba78d6f4632ef1c5228965e3edc8c0faf88c1e Mon Sep 17 00:00:00 2001

Subject: revert(3p/git): Revert merge of git upstream at v2.26.2

This causes cgit to serve error pages, which is undesirable.

This reverts commit 5229c9b232de5bfa959ad6ebbb4c8192ac513352, reversing
changes made to f2b211131f2347342dde63975b09cf603149f1a3.
