Re: git-log to go forward instead of reverse?

Well, this is for a "I'm connected to the net right now: please
refresh all of my git mirrors" script:

        ## (code here to cd to the right dir omitted)
                git-fetch
                if git-status | grep -v 'nothing to commit'

git-status exits non-zero for "nothing to commit" case, so do
not grep its output, but check the status of the command, to see
if your tree is in a good shape to do a pull.

                then echo UPDATE SKIPPED
                else
                    if git-pull . origin | egrep -v 'up-to-date'
                    then git-log --pretty=short ORIG_HEAD..HEAD | cat
                    fi
                fi

The log is just so I can quickly eyeball the interesting changes.

Do we not leave ORIG_HEAD when we are already up-to-date?  If so
that would be confusing...  No, we do leave ORIG_HEAD no matter
what, so you do not have to have this inner if to grep
up-to-date (on the other hand, you might want to do intelligent
things when git-pull fails).  So just drop the if and say
something like:

	else
        	PAGER= ; export PAGER
                git pull . origin &&
                git log --pretty ORIG_HEAD..HEAD |
                git shortlog
	fi

The "cat"
is to keep git-log from starting a pager.  (If there's a switch that does
*that* that I've overlooked, that'd be good too.)

BTW,

        PAGER=cat
        export PAGER

This should work as more efficiently -- see pager.c ;-)
