Git: hooks from configurated path aren't executed

[BaumiCoder]

Steps to reproduce

Preparing a new git repository with hooks. With linux shell for example do this commands:

mkdir testHooks
cd testHooks
git init
mkdir hooks
echo "echo pre commit runs >> precomit.log" > ./hooks/pre-commit
chmod u+x ./hooks/pre-commit
git add ./hooks/pre-commit
git commit -m "add pre commit hook"
git config core.hooksPath ./hooks
echo "some text" > content.txt
git add content.txt

It's importand to change the hook directory. With the default directory .git/hooks there are no problems.

What is the current behavior?

A git commit with rabbitvcs doesn't trigger the pre-commit hook. You can see it, because the precommit.log isn't created.

What is the expected correct behavior?

A git commit with rabbitvcs does trigger the pre-commit hook. You can see it, because the precommit.log is created.
(This also happen if you commit with shell command git commit -m "commit with hook from shell".)
