bug#18044: 24.3; `info-display-manual' should use completing input for manual name

[Samuel Bronson]

I think it would be possible to extract the necessary machinery from the
function `Info-read-node-name' and its -1/-2 friends, but I don't grok
completion well enough to do it myself, and one of the core
(not-info-specific) completion functions involved isn't even documented.
