Subject: diff attribute ignored by show and log -p
Message-ID: <76718490912162046k36e2a275gaf7672b38c7a63e4@mail.gmail.com>

% cat .git/info/attributes
*.xib diff=xibdiff
% cat $(git config diff.xibdiff.command)
#!/bin/sh
trap "rm -f \"$2.tmp\" \"$5.tmp\"" 0 1 2 3 15
ibtool --all "$2" > "$2".tmp
ibtool --all "$5" > "$5".tmp
colordiff -u "$2.tmp" "$5.tmp"

Works great for things like:

% git diff <commit1> <commit2> -- /path/to/*.xib

But is apparently ignored by "git log -p" and "git show" which just
use internal diff. Is this behavior intentional?
