PVS-Studio warning V528 for TortoiseGIT

void
svn_path_splitext(const char **path_root,
                  const char **path_ext,
                  const char *path,
                  apr_pool_t *pool)
{
  const char *last_dot;
  ....
  last_dot = strrchr(path, '.');
  if (last_dot && (last_dot + 1 != '\0'))
  ....
}

Most likely this is what should be written here: "if (last_dot && (*(last_dot + 1) != '\0'))" or "if (last_dot && last_dot[1] != '\0')".

This suspicious code was found in TortoiseGIT project by PVS-Studio static code analyzer.
Warning message is:
V528 It is odd that pointer to 'char' type is compared with the '\0' value. Probably meant: *last_dot + 1 != '\0'. path.c 1258
