[TxMt] VIM features I miss

if a file is mode 444 then you can read it but TM will prompt you to
override when you try to save.  An example of another editor's
behaviour is Emacs.  If the mode is not writable then you can't modify
the buffer.  This would be nice to have in TM, but barring that maybe
a window title notice.  

I guess the way you'd think about it is something like this in
psuedo-python:

if not os.access(file, os.W_OK):
   windowBufferModifiable(False)
else:
   windowBufferModifiable(True)

Then again I just need to be smarter about doing p4 edit first :)
