Bug#998335: debsums: fails to handle files with spaces

That's right. I have the following repo in my sources.list.d/:
deb https://apt.homegear.eu/Debian/ bullseye/

If the package itsself is responsible for the entries in
/var/lib/dpkg/status and if there is a way to escape a space, then the
bug should be filed against the package.

I'm not sure either. But if this regex is greedy, it will stop at the
first space. My version stops before the last space before the md5sum.
That being said, my version will also fail (as will the current version
of debsums) if:
- the name contains spaces and
- the last portion after a space contains digits and a-f
- there is no md5sum (which probably should not happen)
