Option to show a different delimiter in the finder than the one used

[tobx]

I would love to have an option to show a different delimiter in the finder than the one used in the background. This would also solve #314.

Example:

echo '1:2:;3' | sk --delimiter '[:;]+' --with-nth '1,3,2'

This displays 1:32:; in the finder.

Introducing a new option like --display-delimiter could solve that problem:

printf '1:2:;3' | sk --delimiter '[:;]+' --display-delimiter ' : ' --with-nth '1,3,2'

This could easily display 1 : 3 : 2, because junegunn/fzf#2154 (comment) would not be a problem in this case.

This would also enable users to use a "safe" delimiter like NUL and display a human readable delimiter in the finder.
