-These functions implement the \.{\\mubyte} code to convert
-the multibytes in |buffer| to one byte or to one control
-sequence. These functions manipulate a mubyte tree: each node of
-this tree is token list with n+1 tokens (first token consist the byte
-from the byte sequence itself and the other tokens point to the
-branches). If you travel from root of the tree to a leaf then you
-find exactly one byte sequence which we have to convert to one byte or
-control sequence. There are two variants of the leaf: the ``definitive
-end'' or the ``middle leaf'' if a longer byte sequence exists and the mubyte
-tree continues under this leaf. First variant is implemented as one
-memory word where the link part includes the token to
-which we have to convert and type part includes the number 60 (normal
-conversion) or 1..52 (insert the control sequence).
-The second variant of ``middle leaf'' is implemented as two memory words:
-first one has a type advanced by 64 and link points to the second
-word where info part includes the token to which we have to convert
-and link points to the next token list with the branches of
-the subtree.
-
-The inverse: one byte to multi byte (for log printing and \.{\\write}
-printing) is implemented via a pool. Each multibyte sequence is stored
-in a pool as a string and |mubyte_write|[{\it printed char\/}] points
-to this string.
