But as at least one released version of GNU diff has a pretty serious
bug,
I would rather not rely too much on diff. (BTW this was the reason I
wanted --no-index so badly.)
So yeah, the second "diff" cannot be "git diff". Maybe "cmp", but not
"git diff".
Well cmp would be fine as well, seeing all we want is a boolean "is
this the same or not" answer. (I'm not familiar with the GNU diff bug
you speak of, but was it so bad that it couldn't even get *that*
answer right?)
Heh, there's at least one distribution out there (Suse 10.1) that comes
with a *cmp* that doesn't get that answer right if its output is
connected to /dev/null, which is the case when you simply 'make test'.
Yeah. That's what it was. I even posted a patch to GNU diff, only to
find out that it was already fixed in CVS. Sigh.
Wait. Are you still talking about diff or cmp, or are you saying that
your earlier statement about avoiding GNU diff due to its bugs is
unfounded?

I do not remember offhand. I only remembered that it was the GNU diff
package. But maybe it was only the "cmp" tool. Symptoms were that tests
were failing without "-i", but succeeding with "-i".
Okay, I found the mail:
http://article.gmane.org/gmane.comp.version-control.git/25107/match=cmp
Seems it was only "cmp".
Sorry for the noise,
