Bug#920314: lintian: vcs-field-has-unexpected-spaces has false positives

I think all of these are false positives except for rust-num-cpus.

https://lintian.debian.org/tags/vcs-field-has-unexpected-spaces.html

In particular, -b or --branch should be allowed for Vcs-Git (but not
Vcs-Browser). One usecase is tot have a separate branch for each
Debian series.

Because you can then use
git clone https://salsa.debian.org/gnome-team/atk.git -B debian/jessie

It looks like hg works the same way.

Thanks,
