18. Bash no longer requires that the body of a function be a group command;
any compound command is accepted.
19. As of bash-3.0, the pattern substitution operators no longer perform

way the pattern removal functions behave, and is more consistent.
20. After bash-3.0 was released, I reimplemented tilde expansion, incorporating
it into the mainline word expansion code. This fixes the bug that caused
the results of tilde expansion to be re-expanded. There is one
incompatibility: a ${paramOPword} expansion within double quotes will not
perform tilde expansion on WORD. This is consistent with the other
expansions, and what POSIX specifies.
