Linter: no-else-return failing to detect return in this case

[NathanLovato]

There is a bug in your linter that causes it to not recognize that the designated block can fail the if statement and skip the return statement:

1. The incorrect warning is:
   “WARNING on line 75 (no-else-return)
   Unnecessary 'else' after 'if'/'elif' blocks that end with 'return'”

2. The code that triggered this error is:
   ...
   #Return false if vector_angle falls between start_arc and end_arc.
   #This will ensure that weapons can only fire within their designated arcs.
   if end_arc > start_arc:
   if vector_angle > end_arc or vector_angle < start_arc:
   return false
   else:
   if vector_angle > end_arc and vector_angle < start_arc:
   return false

   #Ensure target is within range
   if vector_to_target.length() > ability_range:
   return false
   else:
   return true
