[gentoo-portage-dev] [PATCH] isolated-functions.sh: Do not define any aliases.

[Ulrich Müller]

save_IFS and restore_IFS are the only aliases that Portage defines,
and they are used exactly once. Rewrite __source_all_bashrcs() not to
depend on them, and remove their definitions.

The intention is to drop the expand_aliases shell option at some time
in the future.
