With this patch applied, repeatedly try to
- make sure "foreign" ref does not exist; and - attempt pushing the HEAD:foreign to create the "foreign" ref
until it fails, I can get it stop before the output scrolls off of my 114 line terminal. Then when I revert the changes to transport.[ch] and builtin/push.c in this series, the test will keep going.
Wait. The sample hook used in the test _is_ fed some input but it exits without reading any. What happens when we fork it, and it completes execution before we even have a chance to feed a single byte? Wont' we get a sigpipe and die?
Yup, I think that is what is missing from run_pre_push_hook() implementation.
