Breaks when a directory exists without git subtree

[aminvakil]

When there is already a folder containing a package with the name of pkgname, it will break as it thinks it has already been included.

Lines 142 to 148 in 11aeeaa

	# test if prefix already exists
	if is_package_in_git ${package}; then
	git subtree split -P "${package}" --rejoin
	git subtree pull -P "${package}" aur:${pkgbase}.git master -m "Merge subtree '${package}'"
	else
	git subtree add -P "${package}" aur:${package}.git master
	fi

Can't is_package_in_git improve to check this too?

	is_package_in_git() {
	git ls-tree -d --name-only HEAD | grep -qxF "${1}"
	}

I have found this command to check configured git subtrees: git log | grep git-subtree-dir | tr -d ' ' | cut -d ":" -f2 | sort | uniq, but it will already break if subtree has been added and folder removed later, so I'm not sure about this.
