Hi,
Is this a bug in git-diff? The git-diff-files.html says:
" When the environment variable GIT_EXTERNAL_DIFF is not set ...
For example, if you prefer context diff:
GIT_DIFF_OPTS=-c git-diff-index -p HEAD "
This doesn't work for me with git-1.4.4:
$ unset GIT_EXTERNAL_DIFF
$ export GIT_DIFF_OPTS=-c
$ git-diff-index -p HEAD
diff --git a/configure.ac b/configure.ac
index 74901dc..d222ded 100644

(Really, while I find -u diffs fine for tiny changes, I find them unreadable
for rewrites of larger blocks, and cannot live without -c for these.)
When I look at diff.c around
const char *diffopts = getenv("GIT_DIFF_OPTS");
it appears that only unified diffs are supported??
