Running "git diff" without any settings that would indicate which pager to use causes git to call more instead of less.  more doesn't render the colors so the display is essentially broken.  The git core.pager config and/or $PAGER could be set to tell git to use less.  However, this is not the standard behavior of git and since less is a pre-requisite for installing git there's no reason to default to more.

I was using a copy of git that I had compiled myself and didn't have this problem.  I've confirmed the problem exists in at least the last two versions provided by IBM (git-2.20.1-1.aix6.1.ppc.rpm and git-2.18.0-1.aix6.1.ppc.rpm) so I assume the problem is in IBM's build environment, probably the configure script picking up something it shouldn't.

Thanks for reporting the issue. 

I see this in config.mak.uname file which is used by Makefile.

ifeq ($(uname_S),AIX)
    DEFAULT_PAGER = more
 

For AIX, the default pager is set to "more".  Looks like one can override this setting with the configure option --with-pager=VALUE (with VALUE being less or equivalent ). 

As you said, using "less" as the default pager will be better. In the future builds of git, we will make the default pager to "less" .

This is fixed in git 2.20.2 and is now available in AIX Toolbox
