Repeatable crash in latest zsh

Repeatable crash in latest zsh

[Bart Schaefer]

This has been happening for about a week, I think, so it isn't something
from the most recent patches, but it still happens even with everything
posted so far.  This input:

zsh% setopt completeinword
zsh% ZSH=<C-b><TAB>

(that is, expand-or-complete before the '=') causes `zsh -f` to crash.

The code was to eager to restrict the things to `the string after the
equal sign', forgetting to test if it was after it.
