Bug#784942: autopkgtest: fails to read Files: from perfectly valid .changes file

[Martin Pitt]

Control: tag -1 pending

Hello all,

thanks for the .changes attachments! I can indeed reproduce this now.
Not under Ubuntu, as we have an older python3-debian (0.1.22) -- with
this version it works just fine. But I do get the error with
python3-debian 0.1.27 in sid.

That's indeed the culprit. The workaround to filter out intra-line
comments (line 189) was necessary up to python-debian 0.1.22 due to
https://bugs.debian.org/743174 . 0.1.23 and later fixed some, but not
all, of this. But since autopkgtest needs to run on older releases
too, and even the latest python-debian doesn't accept all kinds of
comments I can't just drop this.

So I refined the parser now to handle lines which consist only of
whitespace and a comment, which seems to work well with older and
newer python-debian:

  http://anonscm.debian.org/cgit/autopkgtest/autopkgtest.git/commit/?id=54744c1b2

(including test case)

Thanks!

Martin
