' (tick) for fig-Forth used -FIND and appears to have
left a clean stack.  -FIND is an immediate which compiles
the xt directly.

-FIND ( pfa b ft | ff )

Other Forth's might use a sequence similar to this for
' (tick) to work with ANS' FIND:

: ' BL WORD FIND DROP ;

"
6.1.1550 FIND CORE (c-addr -- c-addr 0 | xt 1 | xt -1 )

Find the definition named in the counted string at c-addr.
If the definition is not found, return c-addr and zero.
If the definition is found, return its execution token xt.
If the definition is immediate, also return one (1),
otherwise also return minus-one (-1).  For a given string,
the values returned by FIND while compiling may differ
  from those returned while not compiling.
" - ANS 94

So, it's likely that c-addr, the original address of the
counted string to be found by FIND, will be returned or
remain on the stack if a user "fat-fingers" tick, unless
an extra IF-ELSE is used to check the state of the flag
to also DROP c-addr.

Obviously, this depends on the implementation.

BTW, when posting to Usenet via Google Groups, your lines
should be wrapped at 72 to 75 characters.  I fixed your
line lengths for you.  You might consider wrapping them
even shorter so that a few levels of replies indent correctly.
