We have written a diff to our ls(1) to recover the traditional behaviour
of -f implying -a. This change does not only accommodates POSIX.1
but also matches traditional UNIX.

Log message:
restore the traditional behavior of -f implying -a; apparently Keith Bostic
forgot to restore it when the -f flag was put back on 2nd of September 1989,
after being removed on 16th of August as a consequence of issues getting it
working over NFS, so deviation from traditional UNIX behavior in all BSDs
looks like an historical accident; as a side effect, this change accommodates
behavior of this option to IEEE Std 1003.1-2008 (``POSIX.1'').
joint work with jmc@ (who found the inaccuracy in our implementation),
schwarze@ (who provided a detailed tracking of historical facts) and millert@

ls.1:
- Sort options in `SYNOPSIS', the option list, and texts within
the man page;
- improve wording;
- improve macro usage;
- use more consistency regarding (locations for) information about
which options override which;
- cross-reference `-d' and `-R';
- simplify description of `-k', removing redundant and unneeded
information;
- sort entry type list (but leave `-a' and `-A' as they are, given
their meaning);
- correct / augment description of `BLOCKSIZE' environment variable
in `ENVIRONMENT' section;
- bump date.
ls.c:
- Sort options in `usage';
- augment comment about when to figure out block size.
"Modify the man page to match the behaviour of "ls -q",
(done by yamt@ previously)
...
modify both the behaviour and documentation for "ls -b" and "ls -B" to
make spaces readily apparent. This could be done by adding VIS_WHITE
to the flags passed to strvis(3) in the safe_print() function in
src/bin/ls/util.c."
'ls -b' now yields foo\sbar (whitespace) foo\tbar (tab) foo\rbar (CR).
'ls -B' now yields foo\040bar foo\011bar foo\015bar.
suggested by uwe@, inspired by FreeBSD. The three flags override
each other (and the '-q' flag) and behave as follows:
-B Force printing of non-printable characters in file names as
\xxx, where xxx is the numeric value of the character in octal.
-b As -B, but use C escape codes whenever possible.
-w Force raw printing of non-printable characters. This is the
default when output is not to a terminal.
