False positive for Style/RedundantLineContinuation

[marocchino]

I found more edge case for this lint.

Expected behavior

No offence.

Actual behavior

$ ruby -e 'puts "a = b \\\n   || c"' | bundle exec rubocop --stdin test.rb --only Style/RedundantLineContinuation
Inspecting 1 file
C

Offenses:

test.rb:1:7: C: [Correctable] Style/RedundantLineContinuation: Redundant line continuation.
a = b \ ...
      ^

$ ruby -e 'puts "a = b \\\n  if c"' | bundle exec rubocop --stdin test.rb --only Style/RedundantLineContinuation
Inspecting 1 file
C

Offenses:

test.rb:1:7: C: [Correctable] Style/RedundantLineContinuation: Redundant line continuation.
a = b \ ...
      ^

$ ruby -e 'puts "a = b if c \\\n ||  d"' | bundle exec rubocop --stdin test.rb --only Style/RedundantLineContinuation
Inspecting 1 file
C

Offenses:

test.rb:1:12: C: [Correctable] Style/RedundantLineContinuation: Redundant line continuation.
a = b if c \ ...
           ^

Note that 1st, 2nd one maybe duplicate of #12793

I've opened #12798. The case regarding if is likely to be fixed in #12793.
