Description

It appears that john.conf setting NoLoaderDupeCheck = Y has effect on the --show=left option, speeding it up for huge hash lists, yet the corresponding command line option --no-loader-dupe-check isn't currently allowed in this combination. It probably should be.

Research direction

Start by tracing how --show=left handles the NoLoaderDupeCheck setting and where command-line options are checked for compatibility. Compare that path with --no-loader-dupe-check; done means the two options can be used together and retain the speedup observed with the john.conf setting.
