Show the full patch for a git merge commit

Use the undocumented -m and -p options to show the main commit ID.
Why are these not in the help!?

git show -m -p 25172c1

Specify git config temporarily for one command

Use -c after the git call, before any other options:

e.g. to override your core.pager="less -r" setting:

    git -c 'core.pager=cat' log -n 3 --abbrev-commit
