fix quote within quotes formatted incorrectly by fmt

[keystroke3]

Fixes #6998 by looking for `" and "` patterns. If the first quote character is encountered before the second one, then the second character is treated as quoted and the outer quote block ends there. If the second character is encountered before the first, then the inner quote is considered closed, but the other one is not closed. So after the second " in `"" we are still in backtick block. For `"` we are not within any quote block after the last `

I think it could be easier to change quoted to not be a boolean but instead a rune and then check if it's 0 to mean not quoted. Then you just need two conditions very early in the loop if quoted == '"' && ch == '`' and vice versa to just eat the character as-is until the matching quote is found

That's actually a great idea @francislavoie

Sorry for the late reply. I will modify the code and update the pull request.

Oh this is going to be a nice addition! :)

[francislavoie]

@keystroke3 any interest in finishing this up?

[keystroke3]

Apologies for the delay in delivering the fix, life got in the way. I will attempt to work it and deliver by the end of next week. If I can't, then I will update the issue as such so someone else can pick it up.

I still want to fix this, I will need more time, hopefully this weekend I can make some time. Thanks for the patience.

I need to synchronize with the repo, so I will create a new pull request.

OK, I tried the suggested way of using a rune, but it proved more confusing for me to implement. So I used a string instead and checked the cases five we can have; no quote, backtick, quote, quoted backtick and backticked quote:

'', '`', '"', '"`', '`"'

If you feel the suggested way is better, please feel free to reject and re-write as you see fit. I would also like to see how the suggestion looks like.
Thank you for your patience and the person who raised the issue as well.

Nice, I think that'll work... at least better than what we had before!
