My reading was that the OP explicitly wanted to just glance at a single integer number and use it right away in a subsequent rebase command. I mean, use one's own short memory instead of copying and pasting. The way I decided to format the reference in my sketch script — using HEAD~<n> — is just a byproduct of the fact I was aware both of the "gitrevisions" manual page and the fact `git name-rev` exists (though I regretfully was not aware it's able to process a stream of `git log`). Hence while getting fancy names for revisions would be technically correct but less error-prone for retyping from memory ;-)
