Note, however, that for example in /usr/lib/portage/bin/ebuild.sh, it's
always quoted (except once, which looks like an oversight).  Example:

ebuild.sh:1081: if [ "${PORTAGE_BUILDDIR}/.tested" -nt "${WORKDIR}" ];
then

or

ebuild.sh:1090:         cd "${WORKDIR}"

(The line that looks like an oversight is:

ebuild.sh:1019: if [[ ${PORTAGE_BUILDDIR}/.compiled -nt ${WORKDIR} ]] ;
then
)
