Subject: [PATCH v4 0/2] diff --no-index: support symlinks and pipes

git diff <(command1) <(command2) is less useful than it could be, all it outputs is:

diff --git a/dev/fd/63 b/dev/fd/62
index 9e6542b297..9f7b2c291b 120000
--- a/dev/fd/63
+++ b/dev/fd/62

-pipe:[464811685]
\ No newline at end of file
+pipe:[464811687]
\ No newline at end of file

Normal diff provides arguably better output: the diff of the output of the
commands. This series makes it possible for git diff --no-index to follow
symlinks and read from pipes, mimicking the behaviour of normal diff.

v1: http://public-inbox.org/git/[email-masked]/
v2: http://public-inbox.org/git/[email-masked]/
v3: http://public-inbox.org/git/[email-masked]/

Changes since v3:
Using the --dereference option without being in explicit or implicit no-index
mode is no longer silently ignored, but an error. A test has been added for
this behaviour.

Dennis Kaarsemaker (2):
  diff --no-index: optionally follow symlinks
  diff --no-index: support reading from pipes
