Fix #27014: ctrl-A, ctrl-C, ctrl-V breaks formatting of script

This bug was caused by tabs->spaces conversion. Change pate-ing logic to
paste buffer AS-IS (without any conversions).

This commit also fixes undo-ing block deletion which contains tabs when
"Tabs as spaces" is toggled on. Also, markes shouldn't be moved after
pasteing new buffer.
