Great! Do you mean something like
--sort-first-directory-entries=n (with default 100, and
possibly "unlimited"), default default being
--sort-first-directory-entries=0 if --sort-first-directory-entries
is not specified

or

--sort-directory / --no-sort-directory
with 100 not settable on the command line, and an array of
100*(PATH_MAX+1) statically allocated in the code?

I would prefer to avoid the second one of course because i'd like
to be able to easily raise 100 if needed (recompilation is okay).

In addition, "always" sorting is IMHO bad idea for people used
to get their 10000 files in directory order since ages.
