$__git_cmd_idx can be empty in some situations, which leads to
errors when using "git add <tab>", "git mv <tab>",
"git tag <tab>" and "git branch <tab>".
"git mv <tab>" prints this error:
__git_count_arguments:5:
bad math expression: operand expected at `""'
_git_mv:[:9: unknown condition: -gt
"git branch <tab>" prints this error:
_git_branch:[:4: unknown condition: -lt
"git tag <tab>" prints this error:
_git_tag:[:3: unknown condition: -lt
"git add <tab>" prints this error:
__git_find_on_cmdline:[:13: unknown condition: -lt
Fix _git_branch, __git_find_on_cmdline and _git_tag by
initializing the local "c" variable to 1 when empty.
Fix __git_count_arguments by initializing "__git_cmd_idx" to 1.
Adjust the for loop in __git_count_arguments to avoid quoting
the numeric argument to avoid the following error:
__git_count_arguments:8:
bad math expression: operand expected at `"1"'
This was tested on zsh 5.7.1 (x86_64-apple-darwin19.0).

This is not the correct location to fix this, it's here:
diff --git a/git-completion.zsh b/git-completion.zsh
index 0ef15ff..df98e68 100644
--- a/git-completion.zsh

Commit 59d85a2a05 (git-completion.bash: use $__git_cmd_idx in more
places, 2021-04-22) broke zsh because it modified __git_main, but not
__git_zsh_main.
Cheers.

Sweet, thanks Felipe.
The resulting patch is much simpler now too. Please disregard the
previous patches, v2 is on the way.
