of storing it into the files[] array.
- Made flist_find() return "no match" if the found item differs in
  its directory-ness from the search item.
- Changed f_name_cmp() to sort sub-directories after non-directories
  for each directory's contents.  This makes things like the upcoming
  --fuzzy patch easier to get right.
- One complicating factor is that clean_flist() needed some extra
  code to ensure that a directory doesn't duplicate a non-directory
  of the same name.
- Make sure that the "strip_root" code in clean_flist() (for relative
  paths) strips off all leading slashes.

trying to stat() any items inside that dir's hierarchy.  This fixes
a bug where a symlink to a dir getting replaced by a dir with
identical contents to the dir at the other end of the symlink would
not report the updated files in the new hierarchy. (See bug #1673)

(i.e. exclude patterns only) and side-restricted filter rules.

rules.

  apply to the indicated (sender/receiver) side.
- Added the hide/show and protect/risk filter rules as an alternate
  way to specify sender-/receiver-specific include/exclude rules.
- send_rules() now allows f_out to be -1 to indicate that the list
  should be scanned but not sent.
- send_rules() now filters the list to remove any items that don't
  apply to the current side (after sending the item to the other
  side when f_out != -1).
- {send,recv}_filter_list() now transfer the list, even when the
  receiver is the server and --delete-excluded was specified (the
  exchanged list is appropriately filtered, of course).
- recv_filter_list() uses send_rules() to trim non-applicable rules
  when we're a local-server (because we got our filter list without
  send/recv calls when fork() duplicated it).

- Updated MATCHFLGS_FROM_CONTAINER.

when --delete-excluded is set because our list has been trimmed to
only include rules that apply in the current mode.

  of all the conditional code to support that.
- Improved the comment before send_directory() to indicate that it
  gets called with f == -1 from delete_in_dir().

- Improved --partial-dir.

define RULE_MATCH() being changed into RULE_STRCMP().

  have been refused on the server daemon.  This allows us to reject
  implied options (e.g. if --partial is refused and -P specified).
- Changed the handling of the --delete refusals from the old idiom
  of upgrading "delete" to "delete*" into the new idiom of checking
  if refused_delete is set when we determine --delete was implied.
- Changed the --del option from a popt alias into a normal option.
- Mark all the daemon options as refused when a daemon is parsing
  the over-the-socket options.
- Created a new function, create_refuse_error(), which is now called
  from all the spots that check for refused options.
- Don't call clean_fname() on an empty string -- either reject it
  or handle it without erroneously expanding the string.
- If --delay-updates was specified without a --partial-dir option,
  don't send the default "--partial-dir=.~tmp~" option if the server
  is the receiver -- just let it default.

different for protocol version 29.

- Modified f_name_cmp() so that, beginning with protocol 29,
  it will guarantee that a directory name will sort one slot
  before its contents (prior versions could sort other items
  in between in rare instances).

- Only parse the "!" token when MATCHFLG_NO_PREFIXES is set if
  MATCHFLG_CVS_IGNORE is also set.

- Improved safe_fname() so that it changes all non-printable chars
  into '?'s, and accomodates more simultaneous (and longer) names.
