Style/StringConcatenation autocorrect triggers Lint/Syntax error #14499
Description
Style/StringConcatenation incorrectly autocorrected the following excerpt of code, causing a syntax error:
autocorrect(node, "File.open(\"#{path}\")" + '.each_line("\n").to_a.join.split(/\n{2,}/).reject { |e| e.empty? }.reverse.map_with_index {|e, i| i == 0 ? e : "#{e}\n\n" }.reverse')I've isolated it down to what i'm fairly certain is the same issue:
Expected behavior
Style/StringConcatenation to work properly and not create syntax errors.
Actual behavior
