OK, now we just need to do something similar for this:

torch% alias '{'=echo
torch% {bar
zsh: command not found: echobar
torch% fc -l
    1  alias '{'=echo
    2  {echobar

That must be the same problem as the "!!echo" in my $( !! ) example, no?

Here's a test, which I have dropped in the previously-unused "W" category
for "builtin interactive commands and constructs".  If that doesn't seem
correct, rename to D10history.
