I thought that I made it absolutely clear that I like the addition,
too.  If it wasn't clear enough, I can say it again, but I do not
think you need it ;-).

The "attribute" thing was an idea that was hoping to make the system
as a whole even more helpful; if pattern matching with paths is
sufficient for projects to hint desired permission bits per paths,
then those working on such a cross-platform project on Windows do
not have to even worry about "git cmd --chmod=+x", whether cmd is
add or update-index.  If they can just do "git add" and need to use
the new "--chmod=+x" option only when the patterns are not set up
correctly, wouldn't that be even more helpful?  In other words, it
wasn't "with this we can _eliminate_ need for 'add --chmod'".

The only thing I was unsure about that scheme was if "pattern
matching with paths" is sufficiently powerful (if not, such an
addition would not work as a mechanism to reduce the need for the
users to run "git add --chmod=+x").  And that was my inquiry.

Unfortunately, your answer does not help answer that question;
it was a question to Edward, so that's OK anyway.
