Fix bug reported today by Mike Frysinger: mkdir -pv is logging the

wrong file name in some cases.
* src/install.c (struct install_options): New type.
(install_file_in_file_parents, main):
Use it instead of struct cp_options.
(process_dir): Remember the full name.
(announce_mkdir, make_ancestor): Use the full name in announcements.
* src/mkdir.c (struct mkdir_options): Add full_name member.
(make_ancestor): Use the full name in announcements.
(process_dir): Remember the full name.
* tests/mkdir/Makefile.am (TESTS): Add p-v.
* tests/mkdir/p-v: New file, to test this bug.
