Subject: [RFC PATCH v2 12/12] submodule: remove the .gitmodules file when it is empty
Date: Thu, 2 Aug 2018 15:46:34 +0200 [thread overview]
Message-ID: <20180802134634.10300-13-ao2@ao2.it> (raw)
In-Reply-To: <20180802134634.10300-1-ao2@ao2.it>
In particular this makes it possible to really clean things up when
removing the last submodule with "git rm".
The rationale is that if git creates .gitmodules when adding the first
submodule it should also remove it when removing the last submodule.
