There is no technical reason for that, because PARSE is specified to
produce an address in the input buffer, so it must not use a counted
string as intermediate storage.   A.6.2.2008 PARSE says:

|2)
|  3) The count character limits the length of the string returned by
|     WORD to 255 characters (longer strings can easily be stored in
|     blocks!). This limitation does not exist for PARSE.

So it was obviously not the intent of the Forth-94 committee to have
this limitation for PARSE, so it probably is a bug in Forth-94 (and
-2012).
