bline documentation error

From the bline documentation page:

int: Sets the bline object to the specified integer value. Any and all pending breakpoint segments are forgotten (i.e. the time is considered 0 and bline immediately outputs the target value).

Says the same thing for float.

But it's not true. It doesn't output the target value until it gets a bang. Same behavior with "$1 0".

Minor, but should be corrected.

Example patch follows (notice also that "$1 0" and "$1 1" produce exactly the same result).
