_normal:26: bad math expression: operator expected at `0 '

[Roman Neuhauser <neuhauser@mail.cz>]

Hi there,

after about six months of using about 0.01% of the goodies zsh offers,
I decided it was time to checkout compinit. The exploration ended up
before it started with an error I don't know what to think about (I can
read some basic shell scripting, but that's about it). Also note that
I've searched the archives, but only found unrelated messages.

roman@roman ~ > compinit                                           102:0

At this moment, I'm supposed to be impressed. :)

    27      cmd1="$command"

    29    elif [[ "$command[1]" = '=' ]]; then

It does that for ^I completion as well. What's up?
