test_description='git conflicts when checking files out test.'
 
# The first test registers the following filesystem structure in the
# cache:
#
#     path0       - a file
#     path1/file1 - a file in a directory
#
# And then tries to checkout in a work tree that has the following:
#
#     path0/file0 - a file in a directory
#     path1       - a file
#
# The git checkout-index command should fail when attempting to checkout
# path0, finding it is occupied by a directory, and path1/file1, finding
# path1 is occupied by a non-directory.  With "-f" flag, it should remove
# the conflicting paths and succeed.
