[Rd] Patch proposal for R style consistency (concerning deparse.c)

[Brian Lee Yung Rowe]

Writing R in a declarative style a la functional programming makes this whole thread go away since you don't need if/else blocks.

Yes, it's necessary at the command line because the parser needs help in guessing when an expression is finished, but is only needed in that case.  Since I can hardly imagine using else at the command line (that many correct characters in a row exceeds my typing skill) it's not an issue for me.  I most certainly would not inflict this construction on my pupils when teaching a class, nor that any break of a long line has to be after "+" but not before, nor other crutches for the parser's sake.  Let them know about the special case of course, but don't sacrifice good coding style the deficiency.
