To me these completion tests don't work as expected unless I "make
install; make test" resulting Git version rather than simply "make
tests".

I have been told this by SZEDER Gábor <szeder.dev@gmail.com> earlier in
the discussion of these patch series:

<quote>
It might be related to a bug in the build process that doesn't update
that auto-generated list of supported configuration variables after
e.g. 'Documentation/config/log.txt' was modified; see a proposed fix
at:

Looks like that's it?

For reference, I've checked all the commits in the series with this
script:

#!/usr/bin/env bash

while read -r rev; do
    git checkout "$rev"
    make clean > /dev/null 2>&1
    commit=$(git log --oneline --abbrev=6 -n1 $rev)
    echo "Make $commit"
    if ! make prefix=$HOME/git -j8 all >/dev/null 2>&1; then
       >&2 echo "Make for commit $rev failed"
       exit 1
    fi
    echo "Install $commit"
    if ! make prefix=$HOME/git install>/dev/null 2>&1; then
       >&2 echo "Install for commit $rev failed"
       exit 2
    fi
    echo "Test $commit"
    if ! make test; then
        >&2 echo "Test for commit $rev failed"
        exit 3
    fi
done < <(git rev-list --reverse "$1")
