From 7d1aaa684d42964b8b287b8c9450184dfd5bce85 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 12 Jan 2016 08:57:57 +0100 Subject: t0060: verify that basename() and dirname() work as expected Unfortunately, some libgen implementations yield outcomes different from what Git expects. For example, mingw-w64-crt provides a basename() function, that shortens `path0/` to `path`! So let's verify that the basename() and dirname() functions we use conform to what Git expects.
