# Rebase has lots of useful options like --whitepsace=fix, which are
# actually all built in terms of flags to git-am.  Since neither
# --merge nor --interactive (nor any options that imply those two) use
# git-am, using them together will result in flags like --whitespace=fix
# being ignored.  Make sure rebase warns the user and aborts instead.
