+       dirname code cleanup.  base_name now behaves more compatibly
+       with POSIX basename when given file names that have trailing
+       slashes, and similarly for dir_name.  Add new primitives
+       base_len and dir_len.  Put the directory-name-related decls
+       into dirname.h.
+
+       * addext.c (ISSLASH, base_name): Remove; now in dirname.h.
+       * backupfile.c (base_name): Likewise.
+       * basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
+       * dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
+       * makepath.c (strip_trailing_slashes): Likewise.
+       * path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN, ISSLASH):
+       Likewise.
+       * rename.c (strip_trailing_slashes): Likewise.
+       * same.c (base_name): Likewise.
+       * stripslash.c (ISSLASH): Likewise.
+
+       * addext.c: Include <dirname.h> after size_t is defined.
+       * backupfile.c: Likewise.
+
+       * addext.c (addext): Use base_len to trim redundant
+       trailing slashes instead of doing it ourselves.
+       But do not trim the last slash if it is not redundant.
+
+       * backupfile.c (find_backup_file_name,
+       max_backup_version): Use base_len instead of rolling it ourselves.
+       Handle the case of "" and (on DOS) "C:" correctly.
+
+       * basename.c: Do not include <stdio.h>, <assert.h>; no longer needed.
+       Include <string.h>, <dirname.h>.
+       (base_name): Allow file names ending in slashes, other than names
+       that are all slashes.  In this case, return the basename followed
+       by the slashes.  This is more general, and can be used in places
+       where the original base_name purposely had an assertion failure.
+       (base_len): New function.
+
+       * dirname.c: Include <string.h> instead of <stdlib.h>.
+       Do not include <assert.h>; no longer needed.
+       Include xalloc.h.
+       (memrchr): Remove decl.
+       (dir_name_r): Remove.
+       (dir_len): Renamed from dirlen.  All callers changed.
+       Rewrite in terms of base_name, for simplicity and consistency.
+       (dir_name): Never return NULL.  All callers changed.
+       Do not include <stdlib.h> in test program; no longer needed.
+       return 0; is fine for test program.
+
+       * dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN):
+       New macros.
+       (base_name, base_len, dir_len, strip_trailing_slashes): New decls.
+
+       * path-concat.c (path_concat): Use base_len to compute
+       base length, not strlen; this means we cannot rely on memcpy
+       to null-terminate.
+
+       * same.c (STREQ): Remove.
+       (same_name): Handle the case where the basename ends in trailing '/'.
+
+       * stripslash.c (strip_trailing_slashes): Return nonzero if
+       a slash was stripped.  Do not strip the last slash after a
+       file system prefix.
