return from trap while reading with readline breaks completion

[Oğuz]

See:

$ ls
foo  s
$ cat s
trap return INT
read -e
$ source s

I press Ctrl-C here and bash prompts me for the next command. Then I
press F and Tab; instead of producing the bell sound bash completes f
to foo. If I press Ctrl-C again it prints "bash: return: can only
`return' from a function or sourced script" and completion returns to
normal.
