It does not make sense to construct an error message if we're not
going to use it, especially when the process involves memory
allocations that need to be freed immediately.

If we know in advance that we won't use the message, not getting it
slightly reduces the workload and simplifies the code a bit.

Do it.

Makes sense.

No need to say this when the above two paragraphs are clear enough,
like in this patch.
