Somehow missed this in the last commit, where I only changed the commentary
to reflect the actual change (plus minor nits). So here's the actual change:

Rather than '-h' suppressing '-s' when using '-l', make it display

After last weeks addition of the '-b' flag, add '-B' and '-w' flags,
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

-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.
