Why?

Usually we leave these kinds of stylistic decisions to the people
actually working on and maintaining the code.

Unless this message is likely to be copied to another function
and it very much does not look like it is, this kind of change
looks like it will just make grepping for the error message more
difficult.

Not that I am working on the code and can speak but this just feels like
a gratuitous change to me and so I am asking questions to make certain
it is actually worth making.
