Select/set current quickfix list by id/number / goto non-current list entry

[blueyed]

1. Currently there appears to be only :colder/:cnewer to select a quickfix list, which uses relative counts (by number), and therefore it is not trivial to select a specific number (that you can get using getqflist({'id': qfid, 'nr': 1}), but you would have to get the current number and then do a relative :colder/:cnewer. I think it would be nice being able to select a specific list by id. Not sure if selection by number is useful, because this might rotate (there are only 10).

2. My use case / idea is to temporarily switch the lists for :cc/:ll (wrapped by a command to go to nearest entries according to the cursor position).
   For this specific use case it would be best if temporarily switching the current list would not be necessary in the first place, i.e. it would be good if :cc / :ll could be called on a non-current list - likely done best through a new function?! - but maybe also :[id]cc [count] could be used?!
   This way plugins could go to next/prev/specific entries from their list, which must not be the one currently being displayed in the quickfix window.

After seeing the reddit discussion about the Vim advent article on the colder command (https://vimways.org/2018/colder-quickfix-lists/), I was thinking about adding the support for jumping to a particular list in the stack. I don't want to add a new command for this. I am looking for ways to extend one of the existing :colder/:cnewer/:chistory commands to support this. Can we extend the :chistory command to take a list number in the stack?

Currently only the setqflist() and getqflist() functions use the quickfix list identifier. The quickfix commands use only the list number in the stack. Changing this will break backward compatibility. We can add support for changing the current entry in a list using the setqflist() function. - Yegappan

Can you try the attached patch which extends the setqflist() and setloclist() functions to set the index of the current entry in a quickfix/location list? Thanks, Yegappan

I've reviewed #3701, but not really tried it - looks good!

As for 1.:

in the stack?

That sounds like a good solution.

This has been merged now. Can you try the latest version of Vim? - Yegappan

Thank you.
I have not tried it yet still, but assume this to be fixed.
