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.
