Reproduction: https://github.com/zjffun/stylus-supremacy/commit/ef5caf219c248c04737f839f5f1075ae729f58de

Found this by accidentally formatting nib: https://github.com/stylus/nib/blob/master/lib/nib/border-radius.styl#L53

Would you clarify what the expectation and reality are?

[zjffun]

input:

body
  background #000 unless false
  background #000 if fals

output:

body {
        background: #000;
 unless (false);

        background: #000;
 if (false);
}

then stylus the output

ParseError: input-formatted.styl:19:17
   15|          display: none;
   16|  }
   17|
   18|          background: #000;
   19|  unless (false);
-----------------------^
   20|
   21|          background: #000;
   22|  if (false);

This will be fixed in v2.14.5. Thanks!
