I've attached my implementation of the do_unindent() function with the
current undo technique.

If i add 4 lines as follows (with whitespace display on):
»   »   »   »   test
»   »   »   »   test
»   »   »   »   test
»   »   »   »   test

If i then mark all 4 lines and unindent them 4 times it removes all the
indentation as expected:
test
test
test
test

If i then undo one time i get:
»   »   »   »   test
»   »   »   »   test
»   »   »   »   test
»   »   »   »   test

What i would expect from one undo is:
»   »   »   test
»   »   »   test
»   »   »   test
»   »   »   test

Do you have any suggestions on how to make it behave like expected
without writing any specialized undo code in do_undo()?
