+
+ There is no automatic conversion, the String "4" is different

+<
+ When {error} is a |List| with one or two strings, these are

+ the line number at which the error was reported. That can be

+
+ {actual} is used as a string, automatic conversion applies.

The result is a Number, which is the width of window {nr}.
{nr} can be the window number or the |window-ID|.
When {nr} is zero, the width of the current window is

An existing window always has a width of zero or more.
