As far as I can see that's the only argument that git-commit passes on
to the commit-msg hook. Can't you just call something like git-status
from the hook or do you need the information passed specifically as an
argument?

I can always get last commit from `.git/COMMIT_EDITMSG'` - a fixed
file. Isn't passing that as an argument a bit pointless?

That's a good question. I don't know. If someone else knows the reason I
sure would like to find out.

I want files I tried to commit specifically passed in as an argument.

There are many different reasons to use hooks. If everything that a hook
could potentially need was passed to it as an argument then a lot of
data would often end up unused. Better to supply as little as possible
and only do more work when it's actually needed.

Are you suggesting me to run some plumbing command, parse the result
and get the required data ? Is there an easier way to get this done?

I wouldn't go as deep as the plumbing, I think git status --porcelain
should work just fine, the output is fairly easy to parse.
