For the record, this is backwards incompatible with git-programs in
$PATH that were expecting the old format (e.g. git-cinnabar releases
using an older version of libgit.a).

What isn't noted there is that we're still parsing the old format in
some cases, see f9dbb64fad (config: parse more robust format in
GIT_CONFIG_PARAMETERS, 2021-01-12).

But I suspect you mean that you have your own parser that expects the
old format only, I didn't find which way it was by grepping
git-cinnabar's sources.

git-cinnabar is using git's libgit.a, so when using a pre-compiled
version built against git < 2.31.0, it fails to parse
GIT_CONFIG_PARAMETERS when used with git 2.31.0.
There's not much I can do apart from releasing a new version.
