Dear Maintainer,

TagSection object gives an incomplete list of dependencies if dependency
list is multi-line and have some comment lines between dependencies.

For example:

$ dget
http://snapshot.debian.org/archive/debian/20150801T033844Z/pool/main/t/tracker/tracker_1.4.1-1.dsc
$ cd tracker-1.4.1/
$ python3
debhelper (>= 9),
               dh-autoreconf,
               pkg-config,
               intltool (>= 0.40.0),
               gnome-common,
               libglib2.0-dev (>= 2.40.0),

Control: tag -1 confirmed

This is to be expected. Multi-line field values cannot have comment
lines in them, sort of. But yes, the control files can.

We can change the code to parse the value with the # lines, but that
won't help anyone, as the build dependency parsing would fail.

So, what we need is a way to strip the comments from the file when
scanning it. But: That's not possible with APT's current architecture,
as far as I can tell.

So, this might take some time to fix.

There's a bug report in APT for it as well, IIRC. That one should
block this one.
