Here's mine:
[user]
name = stephan281094
email = ...
signingkey = ...
[push]
default = simple
[filter "media"]
clean = git-media-clean %f
smudge = git-media-smudge %f
[core]
excludesfile = ~/.gitignore_global
pager = diff-so-fancy | less --tabs=4 -RFX
[alias]
br = branch
co = checkout
c = commit
d = diff
f = fetch
p = push
s = status
st = status
As you can see I'm using diff-so-fancy for displaying beautiful diffs!
