Hi Daniel Shahaf,
Sorry for bothering you.
I tried:
zstyle -e :completion::complete:git-diff:argument-rest: tag-order changed-in-working-tree-files _next_tags
It says:
_tags:16: command not found: changed-in-working-tree-files
_tags:16: command not found: changed-in-working-tree-files
_tags:16: command not found: changed-in-working-tree-files
_tags:16: command not found: changed-in-working-tree-files
.....
I am extremely sorry for disturbing you too much.
Thanks and Best Regards,
Ahmad Ismail
