I am saying that scripted version left the stdin as-is but somehow we
ended up spawning with .no_stdin = 1 in the C-rewrite, which is a change
in established behaviour. It is often called a regression, unless the
change has a very good reason. And I tend to think this particular one
falls into the former.
We should audit how the hooks are called from various commands
re-implemented, comparing the environment the scripted version used to
give them, which includes:
- what directory the hook is run in;
- what environment variables are exported to it;
- what temporary files are visible to them for inspection;
- in what order they are run;
- which file descriptor is connected to what;
I think we already caught some of the environment and ordering issues in
commit and checkout, but I am far from confident to say that what we have
behave identically to the scripted version.
