How to handle false-positive with git-cherry ?

Hi,

I have several "maintainance" branches which are based on different version of my software, which contains only fixes, imported with 'git cherry-pick'.

I use to comparing stable branches to see if one of them is not missing a fix for instance. For that purpose I use "git cherry" of "git log --cherry".

But sometimes git reports me some false-positives because one fix in a particular branch has been slighlty modified when cherry-picking it (because the context has slighly changed between 2 versions of my soft).

Basically I'd like to force git-cherry to assume that the patch-id of a commit is the same as the one it's been cherry picked from even if the diff is not exactly the same.

One way to do this would be for git-cherry to use the string added by "git-cherry-pick -x":

     (cherry picked from commit xxx)

and to handle the indirection in order to calculate the patch-id.

I couldn't find something equivalent of this with git, but maybe I've missed an option... could anybody tell me if something similar already exist ?

Thanks.
