You can change the set of word delimiting characters used by the Text
Edit routines for word wrap calculations and double click selections
by installing a non-zero address of a routine in the field 'wordBreak'
of a TERecord.  The default set of delimiting characters is /00 thru
/20, inclusive.  The routine is passed the address of the first
character of the text in a0, and an offset to the character in
question in d0.  The routine returns with d0 nonzero if the character
is a delimiter.  Also, the status register should be set reflecting
the value in d0.  As a sample, this routine defines delimiters to be
/00 thru /2f, inclusive.

	.text
	.globl	wdbreak
wdbreak:
	cmpb	#/2f,a0@(0,d0:w)
	sls	d0
	tstb	d0
	rts

One thing to remember: defining a period '.' to be a delimiter might
be great for editing C programs, but lousy when word wrapping causes a
period at the end of a sentence to appear on the next line all by
itself.
