[Bug]: pkgcheck doesn't complain if <remote-id> contains tabs or newlines

[emanuele6]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

If you have something like

<remote-id type="github">
	user/repo
</remote-id>

pkgcheck scan doesn't complain about the TAB and newline characters in <remote-id>.

If it is indented spaces instead of TABs, it will complain with BadUrl because it will check https://github.com/%20%20%20%20%20%20%20%20user/repo, but TABs and newlines are completely ignored.

Expected Behavior

It should complain if <remote-id> contains TABs and/or newlines.
