A new way to get a sha1?

Hi all,

When I should fixup or squash a commit, I nearly never remember how to get the sha1 of the commit I want to fixup. Because sometimes HEAD~n is not enough, I make `git log`, copy the sha1 of the right commit and paste it in my git fixup command. So I wrote a perl script to avoid the usage of the mouse. And after discussion with some of my friends, this can be generalized as a generic command line interface tool to get a sha1.

The idea is to have a perl module which run through the log history and print 10 shortlog associated with a number from 0 to 9, and a message below "Select commit [| 0, 9 |] or next row ?" or this kind of message with several options.

So I ask to the community if this module is interesting for git. It can be integrated everywhere a sha1 is requested (git rebase, git reset, ...). IMHO, it can be an enhancement.

So, what is your opinion? Should I make this script a perl module and integrate it in git, or should I just keep it in my own script toolbox?

Thanks for reading and answering,
