Hi again Martin,
This is more to do with org-mode sensu strictu (non-babel). When you
exit a code edit buffer, tabs are automatically converted to
spaces. There is an org-mode variable org-src-preserve-indentation which
already has a few different effects. Perhaps a solution is to add
not_removing_tabs to the effects of this variable, as in the patch
below. I can't think off hand what that's going to break -- anyone?
Dan
