} This is the bug I reported in 17846.

Aha.

} For now, I moved _prefix before _approximate.

I still think the trap behavior is wrong, but as a stopgap we can do this:

Index: Completion/Base/Completer/_approximate
===================================================================
--- _approximate	7 Jan 2002 15:18:19 -0000	1.5

   }
-  trap 'unfunction compadd' EXIT INT
+  trap 'local _x=$?; unfunction compadd; ((! $_x))' EXIT INT

 _comp_correct=1

This won't work in general because (( )) can only return 1 or 0, not
some arbitrary exit code, but it's fine for _approximate.
