Oh, that still fails the second part of the bug report (#115581)
-- smallyes foo bar echoes "foo\nfoo\n..", not "foo bar\nfoo bar\n.."
Fortunately, that isn't triggered by anything (yet). Do you want to
rely on that?
In fact, no combination of 1,*,@ and :-, - manages to work perfectly
for all of bash, ash and zsh ;) Assuming install will use ash or bash,
either *-y or @-y seems like a good pick.
In the following, "y::foo bar:" is the expected result.
[tv@tv ~]$ for shell in ash bash zsh; do export shell; $shell -c 'smallyes_xu() {
YES="${1:-y}"; while true ; do echo "$YES" ; done; }; ( echo $shell; smallyes_xu |head
-1; smallyes_xu ""|head -1; smallyes_xu foo bar|head -1 )|tr "\012" ":"'; echo; done
;echo

[tv@tv ~]$ for shell in ash bash zsh; do export shell; $shell -c 'smallyes_xu() {

-1; smallyes_xu ""|head -1; smallyes_xu foo bar|head -1 )|tr "\012" ":"'; echo; done

Of course, my version works perfectly ;-)
[tv@tv ~]$ for shell in ash bash zsh; do export shell; $shell -c 'smallyes_tv() { if [
"$#" = "0" ]; then YES=y; else YES="$*"; fi; while true; do echo "$YES"; done; }; (
echo $shell; smallyes_tv |head -1; smallyes_tv ""|head -1; smallyes_tv foo bar|head -1
)|tr "\012" ":"'; echo; done ;echo
