If this regular expression is unanchored, it would accept strings like:
do_install_append1
do_install_appendsomelongstring
and treat them like they were do_install_append. Clearly this isn't desirable.
Only one instance of this type of issue was found in OE-Core and has been fixed
so correcting the regexp should be safe to do.
