This often happens to me:
I'm working on a couple related changes at the same time over the course of a day or two, and when it's time to commit, I end up forgetting what changed in a specific file. (This is just a personal git repo, so I'm ok with having more than one update in a commit.)
Is there any way to preview the changes between my local file, which is about to be checked in, and the last commit for that file?
git diff --changed /myfile.txt
And it would print out something like:
line 23 (last commit): var = 2+2 (current): var = myfunction() + 2
line 149 (last commit): return var (current): return var / 7
This way, I could quickly see what I had done in that file since it was last checked in.
