The Trunk: Morphic-nice.1636.mcz

commits-2
Nicolas Cellier uploaded a new version of Morphic to project The Trunk:
http://source.squeak.org/trunk/Morphic-nice.1636.mcz

==================== Summary ====================

Name: Morphic-nice.1636
Author: nice
Time: 7 March 2020, 1:00:59.396856 am
UUID: 605fc13a-057a-4927-bde8-21cfdd770f3e
Ancestors: Morphic-nice.1635, Morphic-ct.1619

Merge Morphic-ct.1619 and fix undo bug when cmd+d immediately follow a backspace

We must first close the TypeIn (closeTypeIn) before changing the selection (even invisibly), otherwise a wrong selection is memorized in the undo history.

Note that the merge does remove the mysterious oldEditor/selectionInterval dance from PluggableTextMorph>>#printIt (self flag: #fixIntervalCache).
I do not understand the problem it tries to fix (unless the purpose was to workaround such undo bug, which it did not).

Morphic-ct.1619:
        Proposal: Unify all doIt related operations in PluggableTextMorph by delegating them to the editor.

This also fixes the fact that certain hooks such as #printIt:result:, #inspectIt:result:, or #exploreIt:result: were ignored when triggering the operation via the textmorph menu instead of shortcut. This is not an expected behavior, is it?
