Bug#977355: UserWarning: cannot parse package relationship "i", returning it raw

[Raphaël Hertzog]

Package: python3-debian
Version: 0.1.35
Severity: normal

The package tracker started to generate annoying messages in its cron job:

/usr/lib/python3/dist-packages/debian/deb822.py:1403: UserWarning: cannot parse package
relationship "i", returning it raw
  ' relationship "%s", returning it raw' % raw)

This is due to a buggy package containing a dependency on "i" (it's
libmagics++-dev, bug filed already) but I don't see any reason for deb822
to fail on this dependency. It's a very short package name that we should
likely not allow in Debian but I don't a reason to not be able to parse
it (in particular when nothing else in the build machinery choked on that
dependency, starting with dpkg-gencontrol).

Please update the __dep_RE regex to accept single-character dependencies:

   1421     __dep_RE = re.compile(
   1422         r'^\s*(?P<name>[a-zA-Z0-9.+\-]{2,})'

Cheers,
