[PATCH v2 0/1] git-add--interactive.perl: Add progress counter in the prompt

Hi git contributors!

I'm Kunal Tyagi. While I was choosing the relevant patches for a commit using the git add -p command, I found that there was no feedback regarding how many hunks from the current file had been processed and how many were left. So I decided to add a small change to the prompt which basically just displays (${current-hunk-id} + 1/${total-hunks}) before displaying the prompt during user interaction. This patch doesn't account for all total hunks, only per file.

I don't know perl so even this one liner might have mistakes. I did test this locally and hope this works for others. Personally, this change feels helpful to me when I have to separate a long list of changes after an erroneous commit.

On the #git-devel freenode channel, I was informed that @dscho is rewriting git-add in C. If so, perhaps a similar change could be added in the rewrite. I haven't seen his patches in detail so I can't comment if it'll be as trivial as in perl.

Regards Kunal Tyagi
