File 0003-dig-actually-handle-commitish-strings.patch of Package b4

From: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
Date: Tue, 14 Oct 2025 10:59:17 -0400
Subject: dig: actually handle commitish strings
References: dig-support
Git-repo: https://git.kernel.org/pub/scm/utils/b4/b4.git
Git-commit: e8937ac7791dfdba5b788ae128588409bb16778c
Patch-mainline: yes

We claim to handle commitish strings, but we actually don't convert them
into commits. Parse the objects into actual commitid's before we treat
them as such.
