As Adam pointed out, the code does do the right thing for other
backslash sequences; it just processes the character on the following
loop iteration.  I'll add a comment to explain this.

I see another issue here, which is that for a zero-length input string
we will do malloc(0) and realloc(foo, 0), neither of which are very
portable.  Will fix.
