URLs not being copied correctly if they include a percentage sign

[jmriego]

Hi! Just started using this script and finding it amazing. It saves so much time typing or copy/pasting with tmux manually.

I found an issue though when copying URLs if they include a percentage sign. For example, something like this wouldn't be copied correctly:
https://github.com/myproject/new?merge_request%5Bsource_branch%5D=newfeature

The reason is that the copied pattern gets piped using printf in hint_mode.sh so it thinks part of that string is formatting. It only copies down to the first percent sign in this case

Thanks!
