That only works if you use a locale where %'d inserts thousands
separators.  If you ever run with LC_ALL=C, the ' flag is a no-op.

But this is actually a GOOD thing!  It means that your interactive shell
usage (typically under something like LC_ALL=en_US.UTF-8) is
human-friendly, while your scripts (at least robust scripts, such as
./configure scripts generated by autoconf) can force the locale to be
sane so that they aren't dealing with unexpected input (not that 'ls -l'
output is very reliable to parse in the first place, but it would be
even less reliable with thousands separators).
