Diego,
thanks for looking at it. i apologize for not having looked at an
"emacs -Q" (and, thanks to Ihor for, a few days ago, having pointed out
how to "emacs -Q" with one's "normal" org version).
: emacs -Q -L ~/.emacs.d/elpa/org-20201012/ -l org
exhibits *half* of the behavior i am
Greg,
I just did a quick test and I cannot reproduce this, the tabs remain on
entering, modifying and exiting block-edit mode.
One question: do you see "Makefile" as the mode when you are editing the
source block? Otherwise I imagine tab-to-space conversion might be taking
place.
