Hello,
By default, 'git diff' produces an output that is often rather
surprising and difficult to grok, here is a simple example:
$ git diff --no-index -- f0.txt f1.txt
diff --git a/f0.txt b/f1.txt
index 3af00a929..35478f7bd 100644
--- a/f0.txt
+++ b/f1.txt
@@ -3,9 +3,6 @@
#endif
#if CANOPEN > 0
IMD_CANOPEN,
-#endif
-#if MDL_LASER > 0
- IMD_LASER,
#endif
IMD_AUTO,
IMD_NONE,
I figured the offender is --indent-heuristic that is described in the
manual as:
Enable the heuristic that shifts diff hunk boundaries to make
patches easier to read. This is the default.
but apparently rather makes patches harder to read, at least at some
conditions. Turning it off helps to get the expected result:
$ git diff --no-index --no-indent-heuristic -- f0.txt f1.txt
diff --git a/f0.txt b/f1.txt
index 3af00a929..35478f7bd 100644

Changing --diff-algorithm doesn't change the outcome.
So the questions are:
- Is there an example of an advantage the option has?
- Is it possible to flip the default?
