From documentation, I would expect --diff-filter to list changes in
the execute bit, but it does not. I hear on #git that this is
intended, though I still do not know how to filter on the execute bit.
Is it impossible?

Looking at the code, I think it's impossible, and one would have to add
a new --diff-filter letter. However, at the very least, the
documentation should clarify this situation. The --diff-filter
explanation says:

  Select only files [...] have their type (mode) changed (T) [...]

which to me indicates that your test case should work. 

That documentation is quite loosely written.  Typechange diff is what T
has always meant, and it never was about the executable bit.  The word
"mode" in that sentence only means the upper bits S_IFREG/S_IFLNK (iow,
masked by S_IFMT).
