Although it does not happen often when it happens is quite a pain having to find a commit that is "most likely" the one used for a specific release.

My idea is adding a function allowing to find the most similar copy traked by git to the current working area, tipicaly changes done to an "off git" copy given to a coworker in the (not very) recent past.

Right now I paste the files to my staging area and check the diffs commit by commit choosing but the procedure is an approximation and really time consuming.

Having this "similarity search" as a UI feature would be really useful.
