bug#68852: 29.2; Woman + grep fails |

To reproduce:
M-x woman RET grep RET
Debugger entered--Lisp error: (search-failed "\\(\\\\{\\|el[
\11]*\\\\}\\)\\|\\(\n[.']\\)?[ \11]*\\\\}[ \11]*")
re-search-forward("\\(\\\\{\\|el[ \11]*\\\\}\\)\\|\\(\n[.']\\)?[ \11]*\\\\}[

(and (re-search-forward "\\(\\\\{\\|el[ \11]*\\\\}\\)\\|\\(\n[.']\\)?[
\11]*\\\\}[ \11]*") (match-beginning 1))
(while (and (re-search-forward "\\(\\\\{\\|el[ \11]*\\\\}\\)\\|\\(\n[.']\\)?[
\11]*\\\\}[ \11]*") (match-beginning 1)) (re-search-forward "\\\\}"))
(let ((from (point))) (woman-delete-match 0) (while (and (re-search-forward
"\\(\\\\{\\|el[ \11]*\\\\}\\)\\|\\(\n[.']\\)?[ \11]*\\\\}[ \11]*")
(match-beginning 1)) (re-search-forward "\\\\}")) (delete-region (if delete
from (match-beginning 0)) (point)) (if (looking-at "^$") (delete-char 1)))
(cond ((looking-at "[^{\n]*\\(\\\\\n\\)*\\\\{\\s *\\(\\\\\n\\)*") (let ((from
(point))) (woman-delete-match 0) (while (and (re-search-forward "\\(\\\\{\\|el[
\11]*\\\\}\\)\\|\\(\n[.']\\)?[ \11]*\\\\}[ \11]*") (match-beginning 1))
(re-search-forward "\\\\}")) (delete-region (if delete from (match-beginning
0)) (point)) (if (looking-at "^$") (delete-char 1)))) (delete
(woman-delete-line 1)))
(let ((from (point))) (if to (delete-region (point) to))
(delete-horizontal-space) (cond ((looking-at "[^{\n]*\\(\\\\\n\\)*\\\\{\\s
*\\(\\\\\n\\)*") (let ((from (point))) (woman-delete-match 0) (while (and
(re-search-forward "\\(\\\\{\\|el[ \11]*\\\\}\\)\\|\\(\n[.']\\)?[ \11]*\\\\}[
\11]*") (match-beginning 1)) (re-search-forward "\\\\}")) (delete-region (if
delete from (match-beginning 0)) (point)) (if (looking-at "^$") (delete-char
1)))) (delete (woman-delete-line 1))) (cond ((string= request "ie") (cond
((re-search-forward "^[.'][ \11]*el[ \11]*" nil t) (woman-delete-match 0)
(woman-if-body "el" nil (not delete)))))) (goto-char from))
woman-if-body("ie" #<marker (moves after insertion) at 29338 in *WoMan 1
grep*> t)
[...]
I could reproduce also on Emacs-30.0.50
Calling re-search-forward with the NOERROR arg in the while loop of
woman-if-body seems to fix the problem:
