* PARSE ( delim-char -- buffer-start buffer-count )

parse a piece of input (not much unlike WORD) and place
it into the given buffer. The difference with word is
also that WORD would first skip any delim-char while
PARSE does not and thus may yield that one. In a newer
version, PARSE will not copy but just return the word-span
being seen in the input-buffer - therefore a transient space.
