When compiling bash-4.2.20 with CFLAGS +=-Werror=format-security,
there is a warning easy to fix :
print_cmd.c: In function 'indent':
print_cmd.c:1397: warning: format not a string literal and no format
arguments

Debian has a patch for this since bash-4.1. I haven't seen the patch
reported so here it is.
