Subject: 29.3; `Info-search-case-sensitively' errors with "Wrong type
 argument: stringp, nil" on failed search
Date: Thu, 28 Mar 2024 17:40:35 +0100

1. Run Emacs with 'emacs -Q'
2. Press C-h i to open the Emacs Info pages
3. Press S (capital s, aka `Info-search-case-sensitively')
4. In the minibuffer prompt, type "emacs" or "remember"

Observed result:

  Wrong type argument: stringp, nil

is echoed in the echo area.

Expected result:

  Search failed: "abcdr"

is echoed in the echo area.

Additional Information:

This happens for searches on any string for which there is
*at least one* case-insensitive match. For example, the string "emacs"
(a case sensitive match would yield 0 results, because the correct
casing is "Emacs"), the string "remember" (the correct casing on the top-level
info page is "Remember").
