Well, cygwin *does* track the executable bit, because it can, and needs
to for acting like a *nix shell.

So what likely happened, is that you converted using Native, and then
ran your later commit, etc using cygwin.

Which is how everything would show up with the executable bit set, and
performance would be really bad.

My personal recommendation is to only use the cygwin version if you
*really* *really* need the executable bit. Usually if you are developing
on windows you don't actually need it.

I agree it would be nice if they played together better. But if that
means going to a lowest common denominator, then it just means losing
everything. I suppose a possibility would be to set a flag in the
checkout indicating that this was a win32 checkout, so cygwin can ignore
permission bits...

Oh, and just doing "bzr revert" would have reset all of the permission
bits. Especially since you knew the tree was freshly converted.
