Careful ... how that's implemented is a bit wonky.

Technically \-processing doesn't happen in the format code; it
happens in a function called new_fs() (sbr/fmt_new.c).  Well,
new_fs() calls normalize(), but you get the idea.  My point is that
by the time fmt_compile() is called all of the \-escapes have been
processed, so fmt_compile() doesn't "see" them.

We already have putlit that doesn't do the whitespace compression, so I
think zputlit makes more sense.
