Stripping the version, which you can do with qatom, is not a good idea
because it will only reinstall the newest version of any slotted
packages. Best to use sed to prefix each atom with =

emerge -1a $(qdepends -qQ P | sed 's/^/=/')

Also, the use of -u in your examples means currently installed packages
will not be re-emerged, unless a newer version is available.
