How to prepare patch for git am which remove a file ?

[Mathieu Malaterre <malat@debian.org>]

Here is a simple setup:

  cd /tmp
  mkdir g
  cd g
  git init .
  wget http://central.maven.org/maven2/org/apache/xmlgraphics/fop/2.1/fop-2.1.pom
  git add fop-2.1.pom
  git commit -m "My First Commit"
  git rm fop-2.1.pom
  git commit -m "Second Commit"
  git format-patch HEAD~
  git reset --hard HEAD~
  git am 0001-Second-Commit.patch
Applying: Second Commit
error: patch failed: fop-2.1.pom:1
error: fop-2.1.pom: patch does not apply
Patch failed at 0001 Second Commit
hint: Use 'git am --show-current-patch' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

What is the black magic to get `git am` to understand this patch ?
Please note that:

$ patch --dry-run -p1 < 0001-Second-Commit.patch
checking file fop-2.1.pom

Thanks!
