Subject: [PATCH] Fix usage of cons cells in grep-find-ignored-files
grep-find-ignored-files is documented to also include cons
cells, not just globs, but there were two places outside grep.el
where we were using it as if it was only a string list.
To fix this, add a helper function named grep-find-ignored-files
which handles grep-find-ignored-files properly and returns the
list of globs, and use it everywhere.
* lisp/progmodes/grep.el (grep--filter-list-by-dir)
(grep-find-ignored-files): Add.
(rgrep-find-ignored-directories): Use grep--filter-list-by-dir.
(lgrep, rgrep-default-command): Use grep-find-ignored-files
function.
* lisp/dired-aux.el (dired-do-find-regexp): Use
grep-find-ignored-files function.
* lisp/progmodes/project.el (project-ignores): Use
grep-find-ignored-files function, if bound. (bug#71115)
