Re: extend diff3 to ignore whitespace differences - here's a patch

[Paul Eggert]

I can see the general motivation, but I still don't see exactly what
you want diff3 to do in that situation.  Here we have a case where
the 3 files differ, but you want diff3 to consider them to be "the same".
In that case, what should it print?  There are 3 different possibilities
for each line.
