There must be an off-by-one error in a check:

  a.b=c
  zsh: command not found: a.b=c

But it does work for anything longer than one character in the first
component such as foo.bar. I was confused when this didn't work for me
this morning because I was sure I had done some tests of assignments.

Yes, that would be good.

I was thinking of things like zle_bracketed_paste, zle_highlight and
ZLE_RPROMPT_INDENT which it'd be nice to have more hidden.
