[Message part 4 (text/plain, inline)]

Hi,
I have the following Emacs Lisp code:

|(progn (y-or-n-p "Test: ") (let ((search-spaces-regexp 
"\\(?:\\n?[\s\t]+\\|\n\\)?")) (y-or-n-p "Test: "))) |

The first prompt from the |y-or-n-p| function appears as expected:

|Test: (y or n) |

However, the second prompt appears differently:

|Test: (‘y’ or ‘n’) |

I’m trying to understand why the second prompt format changes. What 
causes this inconsistency in the |y-or-n-p| prompt?

I suspect it might be related to the |search-spaces-regexp| variable or 
how Emacs handles interactive prompts, but I’m not sure. Any insights or 
explanations would be greatly appreciated!

Best regards,

Gabriele Nicolardi
