The "function" is not out-of-range , I mean that , the "range string"
( such as 1,100 ) before the function is out-of-range.
For example ,
if you define a function like :
function! Foo()
"do nothing
endfunction
Then , you don't run it thought the map key this time ,
but run the function directly by the "range string"
:1,100call Foo()
If there are not 100 lines in your file , the same error warning will
be shown, right ?
And the same thing happens when you map it to a key and press
[number] + [ key ]
As i say before , the vim will convert the [number] + [key] to the sequence
: . , .+[number-1] call Foo()
# "." means the current line
and you can reference more help about "call" via
:h :call
