anyway).  This gives the user an easy way to talk to a restricted
server that has overly restrictive option-checking.

- Fixed messages longer than 63 chars.
- Don't require the presence of a "bc" program.
- Append a newline to the message to make the script easier to call.
- Make extra sure the message outputs without escape interpretation.
- Stick around long enough for a client to reliably get the message.

identical match found in a --link-dest/--copy-dest hierarchy.

- Made the XSTATE_* defines avoid using 0.
- Call !XATTR_ABBREV() in recv_xattr_request().
- Improved the "internal abbrev" error message.
- Fixed the potential for a directory time glitch in xattrs.diff.

that is unchanged on an early file, and changed on a later file.
Added 2 new test cases to ensure this stays fixed.

srcdir will ensure that the builddir has a copy of the proto.h file when
the Makefile found it to be out of date.  This prevents the repeated
building of all the targets when the srcdir's proto.h file is accurate,
but older than the newest .c file.

daemon excludes can't exclude a dot dir.

the need for a FLAG_DOTDIR_NAME flag (used only by make_file()).

warn the user when the file's size is too large for checksum processing.
