sort(1) -uf output inconsistent with manual page

[e.mantel]

REFERENCES:  <826 at ariel.UUCP>

With regard to "f" and several other options, the sort(1) manual page
I'm looking at says:

	"The *ordering* is affected by the following options..."

It is an idiosyncracy of the "u" option that the selection of the line
output from a set of equal lines is not predictable by the user.

The behavior of the "f" option is probably preferable to what ariel!rick
suggests it should be.  If I want to ignore case, I'll just use tr(1)
before I ever turn it over to sort.
