I also get nothing sensible from this?

I also wonder what this means when I do
`C-h v debug-ignored-errors RET' and it says:

    debug-ignored-errors is a variable defined
    in ‘C source code’.

    Its value is
    ("^No word found to check!$" search-failed beginning-of-line 
beginning-of-buffer end-of-line end-of-buffer end-of-file buffer-read-only 
file-supersession mark-inactive user-error)

    Original value was 
    (beginning-of-line beginning-of-buffer end-of-line end-of-buffer 
end-of-file buffer-read-only file-supersession mark-inactive user-error)

What does it mean the value is X, and the
original value was Y?

I certainly never changed it. I search my
entire code and there isn't a single mention of
`debug-ignored-errors'.

Do packs from [M]ELPA change it or do "the
original value" refer to earlier
Emacs versions?

Or what's going on?
