Upgrade bash from 5.2.21nb1 to 5.2.26

Patch 22: It's possible for readline to try to zero out a line that's
	not null-terminated, leading to a memory fault.

Patch 23: Running `local -' multiple times in a shell function would
	overwrite the original saved set of options.

Patsh 24: Fix bug where associative array compound assignment would
	not expand tildes in values.

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 26: The custom color prefix that readline uses to color possible
	completions must have a leading `.'.
