/* The tree of non-recipients is written to the spool file in a form that
makes it easy to read back into a tree. The format is as follows:

   . Each node is preceded by two letter(Y/N) indicating whether it has left
     or right children. There's one space after the two flags, before the name.

   . The left subtree (if any) then follows, then the right subtree (if any).

This function is entered with the next input line in the buffer. Note we must
save the right flag before recursing with the same buffer.

Once the tree is read, we re-construct the balance fields by scanning the tree.
I forgot to write them out originally, and the compatible fix is to do it this
way. This initial local recursing function does the necessary.

structures are built only if read_headers is set true. It isn't, for example,
while generating -bp output.

It may be possible for blocks of nulls (binary zeroes) to get written on the
end of a file if there is a system crash during writing. It was observed on an
earlier version of Exim that omitted to fsync() the files - this is thought to
have been the cause of that incident, but in any case, this code must be robust
against such an event, and if such a file is encountered, it must be treated as
malformed.

Arguments:
