(A temporary measure until some bugs can be fixed.)

  is still inside the missing hierarchy by using a prefix matching func.
- We now handle the failure to remove a file to create a dir the same
  way as a failed mkdir() (skipping the failed dir's contents).

- Added f_name_has_prefix().

- Say "regular file" instead of "file" when itemizing a list of

- Try to avoid "file" in its generic sense, as it is hard to figure
  out when it includes dirs and when it doesn't.

- Define and use ACL_BUMP(), fixing a clash between -A and -x in a

- Tweaked the F_DIR_*() defines to have more consistent names.
- Don't make F_SUM() return a char pointer that is const.

- Moved the permission-fudging code for dirs into recv_generator() to

- Leave a 1-entry gap between incremental file lists so that we can use
  that index value to refer to the parent directory of each file list.
- Set and use the new ndx_end value in the file list.  The incremental
  recursion mode omits dirs in this value (except in the first list)
  since the generator will be using the new "gap" ndx value to process
  each parent dir.

- Added ndx_end value to struct file_list.
