'git apply', 'git apply --index', 'git apply --cached' do different
things, but what they do is not precisely clear, specially since no
other commands has similar distinctions.
With --no-work (--work being the default), it's clear what the option
would do; modify, or not, the working directory.
So, --work (the default), doesn't cause any changes, and --no-work
enables the current --cache if used with --index.
Eventually --work might replace --cache, if these options are
standarized in the whole git toolset.
