Ensuring that the second argument to `is` resides in its own line about zprint

I think this is probably pretty easy, but I'm unsure of what you mean by your last statement about "handles such optional arguments gracefully". If you want to give me a couple of examples of what you want to see with (or without) the "optional arguments", I hope to be able to give you a solid solution to this.

I have added is to the function map as part of :s1.9 and therefore also :sall, so that the third argument will never show up on the same line as the first and second. I expect that this is what you wanted. Give it a try, and if it isn't right, let me know. This is also in the recent push to GitHub for semantic2 that I discussed in #254.

Also in 1.2.5.
