Bash Version: 4.2
Patch Level: 10
Release Status: release

Description:
        man bash says the redirection target can only be a single word but
        bash seems to silently ignore multiple words when no expansions happen

Repeat-By:
        betelgeuse@pena ~/test $ echo foo > a b
        betelgeuse@pena ~/test $ multi="a b"
        betelgeuse@pena ~/test $ echo foo > ${multi}
        bash: ${multi}: ambiguous redirect

Fix:
        I think both cases should give the same error
