Commitcd3da62d24(fix(completion): unescape strings for __fish_complete_list, 2024-09-17) bravely addressed an issue that exists in a lot of completions. It did so only for __fish_complete_list. Fair enough. Unfortunately it unescaped more than just "$(commandline -t)". This causes the problem described at https://github.com/fish-shell/fish-shell/issues/11508#issuecomment-2889088934 where completion descriptions containing a backslash followed by "n" are interpreted as newlines, breaking the completion parser. Fix that. (cherry picked from commit60881f1195)
