Bug#811053: *.poms Should Not Be Required to Ensure Trailing Newline

[殷啟聰]

Actually, not all programs think `debian/libandroid-dex-java.poms` has
a trailing new line. Inside the text, it is like:

`line1\n`

While the version without trailing new line would be:

`line1`

So some program considers this file has one line regardless the
trailing new line.

And the bug is, maven-repo-helper misbehaves when the trailing new
line is missing. The reason why you failed to build
android-platform-libcore is probably because your Git transformed the
new lines between `\n` and `\r\n`. The other maintainer Chirayu Desai
has solved this problem.

Anyway, thanks for your reply!
