This is where I started off, but POSIX doesn't say anything about the
"--dereference" flag. When chown told me to pick either "-H" or "-L", I
thought it was asking me to pick one mode of operation, either
a) chown -R -L, or
b) chown -R -H
In fact, it was asking me to choose one of
c) chown --dereference -R -L, or
d) chown --dereference -R -H
Should "chown --dereference" be equivalent to "chown"? If so, then
chown --dereference -R -H = chown -R -H
is specified by POSIX.
At this point, you could talk me into either interpretation.
