Yes that should only generate one parameter.
The 'problem' is cause because the internal expansion of $p
isn't actually quoted, "$alt ${p:+"$p"}" is needed for that.
Not being quoted means it should be subject to things like filename
globbing.  (someone is going to tell me that is wrong!)(

IIRC the only quoted expansion that can generate multiple parameters
is "$@".
