This change to use the 'info/' directory instead of the 'hooks/' directory is important because the hooks dir could be redirected to the source tree. Modify the test in such a way that this code change would fail due to being unable to write to the internal hooks directory. Signed-off-by: Derrick Stolee <stolee@gmail.com>
Before making the post-index-change logic more advanced for the postCommand.strategy=post-index-change feature, extract the code into a new method that will be easier to update in the future. Signed-off-by: Derrick Stolee <stolee@gmail.com>
The postCommand.strategy=post-index-change config was designed to replace some internal hook usage. This internal hook was more restrictive than the initial feature was designed. Specifically, it ignored index updates that did not update the worktree. With the existing implementation, this causes more work done in the post-command hook than intended. Update the code to write a sentinel file only when the worktree is changed. Signed-off-by: Derrick Stolee <stolee@gmail.com>

The previously-named 'post-index-change' value for
'postCommand.strategy' did the following two things:
1. Avoid running the post-command hook unless the post-index-change
hook _would_ run with a signal that the worktree changed.
2. Avoid running any installed post-index-change hooks.
The additional restriction of the worktree change in (1) makes this name
less appropriate. Also, item (2) seems to be a side-effect that we
should avoid. We would like to allow both behaviors to exist.
Update the value and behavior, including the tests.

Now that we don't skip the post-index-change hook, we don't need to pass the return value as an out-parameter in this method. Signed-off-by: Derrick Stolee <stolee@gmail.com>

This feature was introduced in #736 but had a few pain points that were discovered when testing the full replacement of the existing post-index-change and post-command hooks in our internal environment:
core.hooksPathto point to a directory within the worktree, the sentinel files were being written into the worktree. Write to$GITDIR/info/instead.Tests are added to confirm both of these behavior changes.
