Comments at the end of line continuations

[KyleMit]

Input:

if code == 9 -- \t
or code == 32 -- <space>
   then
    print(code)
end

Output:

if code == 9 -- \t or code == 32 -- <space> then
	print(code)
end

Expected (combine code and comments serially):

if code == 9 or code == 32 then -- \t  -- <space> 
	print(code)
end

Expected (do nothing if removing new line will place executing code inside a comment):

if code == 9 -- \t
or code == 32 -- <space>
   then
    print(code)
end

^{(same as input)}

or do nothing if removing a newline is going to
