Comment 10 for bug 78505

In Ubuntu, we intentionally set things up using binfmt-support so that
users don't have to know to explicitly invoke things using wine; they
can just execute the .exe file directly. (Or, if we don't do this right
now, this is a regression from previous releases and we should fix it;
we certainly do this for .NET executables using Mono.) Disabling the
executable bit would forcibly remove this feature.

Considering that the alternative is fixing what's little more than a
cosmetic bug in Nautilus - all you'd need to do would be to arrange for
Nautilus to act as if that "View executable text files when they are
opened" option is set when the filesystem is mounted umask=007 or
whatever - I'd rather fix Nautilus than change the installer. Changing
the installer for this kind of thing tends to be more difficult to
reverse later when we discover we did the wrong thing. In any case, you
have to fix Nautilus anyway in order to cope with upgraded systems.

Accordingly, I'm reassigning this bug to Nautilus and declining the
installer change.
