Revision 9093

lib/sh/util.sh: import_vars alias and applicable aliases that use it: documented that when used inside another alias 2+ levels deep, it must be run inside a function. this is due to a strange bug in bash where $() expressions in 2-level aliases produce a syntax error when the alias is expanded outside a function.
