    To work correctly, at least EXPONENT and TYPE should always be the
    same for all uses of this macro for any given TABLE.  A secure way to
    achieve this is to never use this macro directly, but use it to define
    other macros, which would then be TABLE-specific.

    The first time through, COUNT is usually zero.  Note that COUNT is not
    updated by this macro, but it should be update elsewhere, later.  This
    is convenient, because it allows TABLE[COUNT] to refer to the new

    The `keyword' pointer provides the central word, which is surrounded
    by a left context and a right context.  The `keyword' and `length'
    field allow full 8-bit characters keys, even including NULs.  At other
    places in this program, the name `keyafter' refers to the keyword
    followed by its right context.
-

    The left context does not extend, towards the beginning of the file,
    further than a distance given by the `left' value.  This value is
    relative to the keyword beginning, it is usually negative.  This
    insures that, except for white space, we will never have to backward
    scan the source text, when it is time to generate the final output
    lines.
