[PATCH v2 1/2] t3103: demonstrate dir.c:treat_one_path() core.ignorecase failure

2eac2a4cc4bdc8d7 (ls-files -k: a directory only can be killed if the
index has a non-directory; 2013-08-15) adds a caller of
directory_exists_in_index(dirname,len) which forgets to satisfy the
undocumented requirement that a '/' must be present at dirname[len]
(despite being past the end-of-string). This oversight leads to
incorrect behavior when core.ignorecase is true. Demonstrate this.
