Subject: [GSoC PATCH] t8003: avoid suppressing git's exit code

From: Trieu Huynh <[email-masked]>
Date: Thu, 26 Mar 2026 23:11:18 +0900

Update t8003-blame-corner-cases.sh to redirect git-blame output
to a temporary file instead of piping it directly to not hide
the exit code of git commands behind pipes, as a crash in git
might go unnoticed.
