I can't reproduce the problem with today's build. In order for C-I as the first character to actually insert a tab, I have to visit a file (emacs -q ~/foo). When I do this, undo works properly and deletes the space.
I can't go firther without a precise test case. Please read the Bugs section in the Emacs manual, which provides guidelines on how to write a bug report to give us the necessary information so we can fix the bug. _______________________________________________ emacs-pretest-bug mailing list [email protected] http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug
