Deadcode breaks multiline assignments

[Freyb]

When deadcode detects an unused variable, it only attempts to remove the line of assignment, ignoring any further lines that are connected to the assignment.

Here, I have an assignment that takes the output of a function call that was broken into multiple lines. Deadcode only tries to remove the first line, leaving the second and the third line in place, resulting in a syntactically incorrect file.

-unused_variable = function_call(
     param1, param2, param3
 )

deadcode version: 2.4.1
