I think this is expected behavior. When you select several lines
in Visual mode and then use : to enter Command-Line mode, a range is
inserted automatically. In the second, simplified, example, try leaving
off the <cr> to see what is happening. What happens then is explained
under
:help :call
For the original example, you have to tell vim that the
user-defined function will handle the range itself (even if the function
decides to ignore the range).
:help function-range-example
(Hey, that is the paragraph following :help :call .) Perhaps a simpler
method is to remove the range. For example,
:vnoremap \\ :<c-u>call input(line('.').col('.').'>>>')<cr>
