This makes it so `complete -c foo -n test1 -n test2` registers *both* conditions, and when it comes time to check the candidate, tries both, in that order. If any fails it stops, if all succeed the completion is offered. The reason for this is that it helps with caching - we have a condition cache, but conditions like ```fish test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] sub ``` defeats it pretty easily, because the cache only looks at the entire script as a string - it can't tell that the first `test` is the same in both. So this means we separate it into ```fish complete -f -c string -n "test (count (commandline -opc)) -ge 2; and contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences" +complete -f -c string -n "test (count (commandline -opc)) -ge 2" -n "contains -- (commandline -opc)[2] length" -s V -l visible -d "Use the visible width, excluding escape sequences" ``` which allows the `test` to be cached. In tests, this improves performance for the string completions by 30% by reducing all the redundant `test` calls. The `git` completions can also greatly benefit from this.
