Re: Simplify internal_catch()

[Chris Gregory]

Here is the updated patch.  I replaced the if statement with a ternary
operator.

> Why place the declaration of `val` between the two?
I'm unsure as to the style desired for Emacs source code.  I've seen
both used in it.  I'll use the declaration initialization in the future
as I also prefer that.
