Re: 23.0.60; Assuming errstring unibyte is incorrect and leads to Emacs crashes

[Richard M. Stallman]

    I still don't understand why that's different: most C applications also
    output those error message prepended with some other text and a colon.

Then they too should downcase the messages, to be othographically
incorrect.  The capital letters are correct if the message appears
as the start of a sentence, but not after other text and a colon.

I made Emacs do it right.
