I'm glad I'm not the only one thrown by this. I remember that the
default behavior is *not* what I want/expect (I'd expect that a
search pattern would *find* the thing I want to sort on), and that
there's some flag that controls that behavior to give me what I
want. But the same with you, I have to look it up EVERY SINGLE TIME.
As best I can tell from ex_cmds.c the "r" stands for
"r[egular e]x[pression]" search ("static int sort_rx; /* sort on
regex instead of skipping it */")

Which is indeed confusing because ":sort" can/does use a regexp even
with this flag set, just for the purposes of skipping instead of
finding the thing to sort.
