[PATCH 1/1] mingw: avoid a buffer overrun in `needs_hiding()`

["Johannes Schindelin via GitGitGadget" <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.
