The style guidelines state that an error message should include the
reason for the error. That is fully intentional, and I would consider
the above to be a step backward.
In fact, every use of %m would fall into your bunch as well. We only
write "could not open file: %m" instead of "could not open file because
%m" for grammatical reasons. I don't think splitting out the %m would
be an improvement.
