I read up on Array.wrap but don't understand why you would choose that implementation instead of Kernel#Array. I am interested to hear why you would go this route instead of reducing this change to:

arr_opts += Array(opts[:parent]).map { |p| ['-p', p] }.flatten

I think calling #to_a if #to_ary doesn't exist would be the desired behavior.

[]
elsif opts[:parents].respond_to?(:to_ary)
opts[:parents].to_ary || [opts[:parents]]
else
[opts[:parents]]
end
parents << opts[:parent] if opts[:parent]

arr_opts = []
arr_opts << tree
arr_opts << '-p' << opts[:parent] if opts[:parent]
arr_opts += [opts[:parents]].map { |p| ['-p', p] }.flatten if opts[:parents]
arr_opts += parents.map { |p| ['-p', p] }.flatten
command('commit-tree', *arr_opts, redirect: "< #{escape t.path}")
end
