$( <Tab> has CURRENT=1, $(( <Tab> has CURRENT=0

$( <Tab> has CURRENT=1, $(( <Tab> has CURRENT=0

Hello,
in both cases words array is empty, so CURRENT=0 seems to be more
logical value. Maybe something bigger is hidden behind this.

Here is a test code that might be employed to see this:

https://github.com/psprint/zsh-editing-workbench/blob/de33867898643e6161dd172db6f8bab42f73083d/widen_for_history

It's enabled with:
autoload widen_for_history
zle -N widen_for_history
zstyle ':completion:*' completer widen_for_history _complete

Outputs of the code for $( <Tab> and $(( <Tab>

A CURRENT: 1, words: ><
B CURRENT: 1, words: >$( <
C CURRENT: 1, CURSR: 2, lft: |$(|, rght: ||, words: >$(<
PREFIX: |$(|, SUFFIX: ||
Calling _history
$(( 0 + 1 )) $(( 0 + 1 )) $(( 試句相當長 ""  $(( 0 + 1 )) $( ( echo b ))
$(( echo b ) ) $(( echo a ) ) $(( 0 + 1 )) $(( 0 + 1 )) $(( i + 1 ))
$(( i + 1 )) $(( i + 1 )) $(( i+1 )) $(( i+1 )) $(( i+1 )) $(( i+1 ))
$(( i+1 ))

A CURRENT: 0, words: ><
B CURRENT: 0, words: >$(( <
C CURRENT: 1, CURSR: 4, lft: |$((|, rght: ||, words: >$((<
PREFIX: |$((|, SUFFIX: ||
Calling _history
$(( 0 + 1 )) $(( 0 + 1 )) $(( 試句相當長 ""  $(( 0 + 1 )) $(( echo b ) )
$(( echo a ) ) $(( 0 + 1 )) $(( 0 + 1 )) $(( i + 1 )) $(( i + 1 )) $((
i + 1 )) $(( i+1 )) $(( i+1 )) $(( i+1 )) $(( i+1 )) $(( i+1 ))

CURRENT=1 indicates the completion is in command position, even if there
is no command present yet.  The command name is always the "first word"
even if that is so far an empty word.

CURRENT=0 only makes sense in contexts where there is no command position
at all.
