    this way, on 32bit systems, strings of up to 3 bytes can be represented with
    just a Lisp_String without any `sdata'.  On 64bit systems, this can be used
    for strings up to 7 bytes long (i.e. almost 50% of all allocated strings,
    IIRC).  And it can also be used for all the strings in the pure space (no
    matter how long), so it saves about 50KB of pure space (can't remember the
    exact number, but IIRC it was more than 10KB and less than 100KB).

Sounds good.
