Correcting typo in render.lisp #142

Closed togekawa5 closed 3 years ago

This was not a typo. The tilde newline directive was there for a reason.

I'm sorry, I forgot ~newline in format. Another reason I thought it was a typo was because this raises an error. When I delete ~newline, that error no longer occurs. I checked that this error does not occur with simple ~newline in format ,for example (format t "a~ b"). My environment is windows10, sbcl2.1.6. The debugger displayed the following.

I loaded sdl2 on macOS as well, it was loaded without any problem. The environment is macOS Big Sur version 11.4, sbcl 2.1.5. I posted it in issue #143.
