Nice, i.e. let's generally fix the output instead.

I haven't thought about this carefully but isn't there some way to
combine these if/else if/if statementsn that's clearer?
I.e. here we're doing an "if" check for a !lineline and then an "if"
that can't be true if !linelen.
Isn't this the same as:
if (!scratch->len) {
...
} else {
if (!linelen)
...
else if (linelen > 0)
...
}
Or are there cases where we take that "linelen > 0" arm if
!scratch->len?
