Favors the line with shorter matched chunk. A chunk is a set of
consecutive non-whitespace characters.
Unlike the default `length`, this new scheme works well with tabular input.
# length prefers item #1, because the whole line is shorter,
# chunk prefers item #2, because the matched chunk ("foo") is shorter
fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF"
N | Field1 | Field2 | Field3
- | ------ | ------ | ------
1 | hello | foobar | baz
2 | world | foo | bazbaz
EOF
If the input does not contain any spaces, `chunk` is equivalent to
`length`. But we're not going to set it as the default because it is
computationally more expensive.

- Not the exact solution to --tiebreak=length not taking --nth into account,
but this should work. And the added benefit is that it works well even
when --nth is not provided.
- Adding a bonus point to the last character of a word didn't turn out great.
The order of the result suddenly changes when you type in the last
character in the word producing a jarring effect.
By not storing item index twice, we can cut down the size of Result
struct and now it makes more sense to store and pass Results by values.
Benchmarks show no degradation of performance by additional pointer
indirection for looking up index.
Make sure to consistently calculate tiebreak scores based on the
original line.
This change may not be preferable if you filter aligned tabular input on
a subset of columns using --nth. However, if we calculate length
tiebreak only on the matched components instead of the entire line, the
result can be very confusing when multiple --nth components are
specified, so let's keep it simple and consistent.
