[David Henningsson (diwic)]

Hi RaduStoica, and thanks for trying to help out!

I gave your merge proposal a quick review as part of the patch pilot program. And I noticed something strange while doing so - your commit does not only add the patch but also applies it, which means changes to files outside the debian directory.

Looking a bit back in history, it seems you're not the only one who has done this. As such I think it would make the most sense to do two commits: the first would just unapply all patches (to correct the previous stuff), the second one would add your patch without applying it (i e, only changes to debian/changelog, debian/patches/series and debian/patches/scroll-alternate-src-togglable.patch).

The actual patch content looks okay to me so hopefully it can be merged (by somebody with the appropriate upload rights, which I don't have) after that.

Thanks for taking the time to look at my branch! I'm still a bit confused about
how the quilt patching works, so that's why I commited the files with the patch
applied.

I've done a new commit now, with all patches unapplied. The patch for scrolling
in ncurses apps is still added in the debian/patches/series file, so I don't
think a second commit is needed. Let me know what's your opinion - I can make
a clean branch and add the patch to that one, if this one seems too messy.

[Iain Lane (laney)]

Thank you, I've merged it and uploaded to Quantal. There was no need to create a new version for the .pc fiddling - the mantra is one version per upload. Anyway, I'm sure I messed that up again while merging. It's complex :P
