So, I bet this was heavily debated back in the year 2011, for #96230... but I
was wrong!  (That's when qr// stopped acting like m//.)

Then I guessed it was debated during the discussion of changing "split / /".
Note that with split, the fix was to make "split /$onespace/" act like
"split / /".  Again, wrong!

In review, though, I think this won't end up being worth it.  Dave's suggestion
(at https://rt.perl.org/Ticket/Display.html?id=124368#txn-1348595 ) seems
sensible, and there's no pressing /need/ to break this behavior, even if it has
occasionally seemed more trouble than it's worth.
