in 27.1 i am not getting this.

i am getting this:

file aaa: now is the time
file bbb: now is the time for all good men

now you diff this
with result:

line 1: -now is the time
line 2: +now is the time /for all good men/

line 1 does not indicate that anything was deleted.  i request that
diff-mode do so, if possible.  line 2 is correct.

what i need is an indication that something is lacking in line 1.  i
do not need the text that is lacking.
