#compdef git-ls-ignored
#description List files which exist and are ignored by this repository.

# Offer the paths the script would actually list, so the candidates match its
# rules rather than the --exclude-standard set used by zsh's own
# __git_ignored_other_files. _multi_parts descends one component at a time, so
# a directory holding ignored files completes as a way to narrow the listing.
