Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

1. Run `git init` in an empty directory, and commit once.
2. Run `git am` and press Ctrl-C.

Doesn't `git am` print a warning about how it's reading from stdin?
Pressing C-d at this point to send EOF just exits "normally."

Indeed

3. Run `git status`. It will say: 'You are currently rebasing. (all
conflicts fixed: run "git rebase --continue")'.

Yes, this is odd: my shell prompt (using the contrib script) says
"AM/REBASE", so I know better: git am --abort does the trick.

This seems like a failure of git-status more than anything; I wonder
if there's some difference in how the prompt script checks for
in-progress am vs. how git-status does it?

I think the issue is that "git am" does not write the ".git/rebase-apply/applying" which "git status" uses to distinguish between "git am" and "git rebase" until it has read the patch files. We could instead check for ".git/rebase-apply/rebased-patches" which is written by "git rebase" but that file gets deleted when "git am" exits for the user to fix merge conflicts. I think the best solution is to move where "git am" writes ".git/rebase-apply/applying" so it gets created before the patch files are read - see the diff below.

Best Wishes
