    Patch 26
	The custom color prefix that readline uses to color possible completions
	 must have a leading `.'.
    Patch 25
	Make sure a subshell checks for and handles any terminating signals before
	 exiting (which might have arrived after the command completed) so the parent
	 and any EXIT trap will see the correct value for $?.
    Patch 24
	Fix bug where associative array compound assignment would not expand tildes
	 in values.
    Patch 23
	Running `local -' multiple times in a shell function would overwrite the
	 original saved set of options.
    Patch 22
	It's possible for readline to try to zero out a line that's not null-
	 terminated, leading to a memory fault.
