We try to stay away from arguments with mixed types. Accepting both a
number and a string makes it harder to give good error messages.
Getting the number of lines in a buffer is a generic thing. line()
already takes an optional window ID argument. It's logical to also
accept a buffer number.
line({expr}, {winid}, {bufnr})
However, that is ambiguous, the {winid} would be ignored when using the
{bufnr}. Perhaps it's better to use:
line({expr}, {id}, {id-is-bufnr})
When the third argument is omitted or FALSE, the {id} is used as the
{winid} like before. When it is TRUE then {id} is used as {bufnr}.
So for your example you can use: line('$', bufnr, 1).
How about that?
An alternative would be to add a bufline() function. Advantage is that
we can drop the window related items, since a buffer by itself does not
have a cursor position or visible lines.
