From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
The 'git sparse-checkout set' subcommand takes a list of patterns
and places them in the sparse-checkout file. Then, it updates the
working directory to match those patterns. For a large list of
patterns, the command-line call can get very cumbersome.
Add a '--stdin' option to instead read patterns over standard in.
