That's right.

When expanding a PU, we look for a canonical including CU, and expand
that instead.  This is handled by the loop in psymtab_to_symtab.

When expanding a CU, we expand all of the PUs it includes (but in
isolation, we don't go "back up the chain" to the canonical CU).  This
is handled by how the symtab reader processes DW_TAG_imported_unit.
