I am using emacs win32 on cygwin. and I encountered this commonly seen 'replace tab with space ' issue on emacs. but slightly different.
I have configured like this:
(setq tab-width 4) (setq indent-tabs-mode nil)
this works well for Pressing Tab. but some times I need to align a block of python code with
Shift + > and using this key combination, I still get the Tab characters in the underlying document.
