An `--ignore-file=` flag would be nice I guess:
--ignore-file=.ignore
--ignore-file=.gitignore
--ignore-file=.dockerignore
--ignore-file=.npmignore
etc
but then, assuming all those share the same "ignore file syntax/grammar"...
--ignore-file=.ignore
--ignore-file=.gitignore
--ignore-file=.dockerignore
--ignore-file=.npmignore
etc
