A variable is not set until it is assigned a value. `declare -p name' only
finds set variables.

Yes, since that is supposed to produce output that can recreate all
variables with their attributes, even unset variables.
This is a common enough request that I have changed the behavior of
`declare -p name' for the next bash release, and it will display variables
that are not set but have been given attributes.
