patch 9.0.1723: Fix regression in {func} argument of reduce() Commit: https://github.com/vim/vim/commit/ad0c442f1fcc6fe9c433777ee3e5b9e6addc6d69 Author: zeertzjq <zeertzjq@outlook.com> Date: Thu Aug 17 22:15:47 2023 +0200 patch 9.0.1723: Fix regression in {func} argument of reduce() Problem: Fix regression in {func} argument of reduce() Solution: pass function name as string again Before patch 9.0.0548, passing a string as {func} argument of reduce() is treated as a function name, but after patch 9.0.0548 it is treated as an expression instead, which is useless as reduce() doesn't set any v: variables. This PR restores the behavior of {func} before that patch. Also correct an emsg() call, as e_string_list_or_blob_required doesn't contain format specifiers. closes: #12824 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: zeertzjq <zeertzjq@outlook.com>
