Source: lintian Version: 2.5.123 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.
