  There is no need to use an intermediate array for these memory allocations,
so, axe it.

While at it, turn a '== NULL' into a shorter '!' when testing memory
allocation failure.

Fair enough!

I have sent some other cleanups to this code only
yesterday, so they might collide and they you might have
to rebase.

Yours,
