Subject: [PATCH 1/1] mingw: avoid a buffer overrun in `needs_hiding()`
Date: Fri, 25 Oct 2019 14:13:36 +0000	[thread overview]
Message-ID: <aaf7bfc54572c6a3cd00eb2034c07a7bf57835fe.1572012816.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.427.git.1572012816.gitgitgadget@gmail.com>

From: Johannes Schindelin <johannes.schindelin@gmx.de>

When this function is passed a path with a trailing slash, it runs right
over the end of that path.

Let's fix this.
