Hi all,
The submatch() function with a second argument set to 1, returns NULL
when used outside of a :substitute command or the substitute() function.
All the other functions that return a List, return an empty List on failure.
But the submatch() function returns NULL on failure. e.g.
call assert_equal([], submatch(0, 1))
echo v:errors
The returned value cannot be compared against NULL. I think the submatch()
function should be changed to return an empty List.
