[Feature request] Highlight replacements in dry-run mode.

[murlakatamenka]

Hi, thanks for rnr!

It would be nice to highlight in color what is replaced with what in a dry-run mode.

Useful cases:

• files / directories with long names (surely human brain parses colors way faster than long symbol sequences, and then you also need to diff both paths!)
• replacement occurs multiple times

That's how ripgrep highlights found matches by default, for instance (rg fn):

Or another toy example (echo barfoobar | rg bar --replace baz):

What do you think?

Yes, this would be a nice addition to rnr. I will take a look at this feature to include it in the next release. Thanks for the feedback!

I added the diff feature in the colored version of the output. It is currently in master but I will include it in the next release.
