You could head N characters from the file to tar xf - to stifle searching farther.
Code:
head -262144c <tar_file | tar xvf - first_file

NAME
git-cherry - Find commits not merged upstream SYNOPSIS
git cherry [-v] [<upstream> [<head> [<limit>]]] DESCRIPTION
The changeset (or "diff") of each commit between the fork-point and <head> is compared against each commit between the fork-point and <upstream>. The commits are compared with their patch id, obtained from the git patch-id program. Every commit that doesn't exist in the <upstream> branch has its id (sha1) reported, prefixed by a symbol. The ones that have equivalent change already in the <upstream> branch are prefixed with a minus (-) sign, and those that only exist in the <head> branch are prefixed with a plus (+) symbol: __*__*__*__*__> <upstream> / fork-point \__+__+__-__+__+__-__+__> <head> If a <limit> has been given then the commits along the <head> branch up to and including <limit> are not reported: __*__*__*__*__> <upstream> / fork-point \__*__*__<limit>__-__+__> <head> Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id. For example, this will happen if you're feeding patches <upstream> via email rather than pushing or pulling commits directly. OPTIONS
-v Verbose. <upstream> Upstream branch to compare against. Defaults to the first tracked remote branch, if available. <head> Working branch; defaults to HEAD. <limit> Do not report commits up to (and including) limit. SEE ALSO
git-patch-id(1) GIT
Part of the git(1) suite Git 1.7.10.4 11/24/2012 GIT-CHERRY(1)
