Alternatively I see that BusyBox ash did this:

            case '\\':
-               pc = pgetc();
-               if (pc == '\n') {
-                   nlprompt();
-                   /*
-                    * If eating a newline, avoid putting
-                    * the newline into the new character
-                    * stream (via the STPUTC after the
-                    * switch).
-                    */
-                   continue;
-               }
+               pc = pgetc(); /* or pgetc_eatbnl()? why (example)? */
