Review comment:
Same as above, if wrapping an error put it at the end.

Review comment:
You probably remember from the other PR, but put errors at the end of
format strings, after a colon.
I forgot to mention why in the other PR. It's Go convention so that you can
see the source errors in sequence and easily be able to read where one ends and
another begins.
