The above fix doesn't work as the quoted version is not interpreted correctly by declare when it is actually run in a git repo.

A fix for this could be to ensure `format_last_commit_here` always returns variable declarations or else exits when git fails - something like:

format_last_commit_here() {
    local format="$1"; shift
    TZ=UTC git log -n1 --first-parent "--format=format:$format" . || (echo "git log command failed - is $(pwd) a git repo?"; exit 1)
}

Or I suppose the version_from_git function could do a sanity check first to make sure it is, in fact, in a git repo.

That example doesn't work either, because subshells.

Now trying this:

declare x=1 $(format_last_commit_here "git_ts=%ct git_hash=%h")
