incremental recursion is active.  Added test.

- Prompt the user for the parameters when missing.
- Allow the creation of a module without a user+password.

Fixed a just-introduced problem with a relative module-path.

- Free a mergelist's parent_dirscanned filters the last time it is
  popped or as soon as the filters are discarded due to the "n"
  modifier.  Aside from not leaking memory, this is needed to clean up
  any mergelists defined during the parent_dirscan to avoid crashing by
  trying to restore nonexistent state for them in pop_local_filters.
- Make push_local_filters save the current mergelist_cnt, and make
  pop_local_filters assert that it has the correct number of mergelists
  before restoring their state.
- Assert that mergelists get deactivated in strict LIFO order to catch
  any glitches as soon as they happen.  Free linked lists of filters in
  reverse order to make that the case.
- Add a bunch of mergelist-related debug output (--debug=filter2).

Also improved the human-readable output functions, including
adding the ability to output negative numbers.

nightly tar file release.  Fixed the opening comments.

mention the protocol number have the right value, that the check-in date
for a protocol-change release is specified, and that a pre-release with
a protocol change doesn't have SUBPROTOCOL_VERSION set to 0.  Prompt for
releasing a branch if -b option was not used and we're on a branch.

I/O error for the incremental directory that generated the error.  The
PROTOCOL_VERSION was bumped to 31 to implement this.

with the msgs2stderr value.

even more solid.

code calls wait_for_receiver().

if the index isn't found.

it now outputs the name back to the client without mangling the charset.

code will not delete in a directory prior to receiving an I/O error
for that directory (or not receiving it, as the case may be).

new enough to do symlink content conversions.

list that is transferred.  This fixes a glitch where a failed
--iconv conversion on the receiving side could prevent deletions
from happening in the root-dir of the transfer.

lone --info=misc2 message into a --debug=iconv message so that
all iconv info will be output when requesting iconv debugging.

- Make sure that handle_partial_dir() never returns a truncated fname.
- Make robust_rename() return that it failed to do a cross-device
  copy if the partial-dir could not be created.

especially important for --delay-updates, particularly when
--remove-source-files was also specified.
