[PATCH] bash: fix string format errors when enabling security flags

[PATCH] bash: fix string format errors when enabling security flags

[Ross Burton]

If security_flags.inc is included then bash 3.2.48 fails to build:

| ../bash-3.2.48/print_cmd.c:1152:3: error: format not a string literal and no format arguments [-Werror=format-security]
|    cprintf (indentation_string);

Backport a patch from upstream to solve this.
