The Inbox: HelpSystem-Core-ct.122.mcz

commits-2
A new version of HelpSystem-Core was added to project The Inbox:
http://source.squeak.org/inbox/HelpSystem-Core-ct.122.mcz

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

Name: HelpSystem-Core-ct.122
Author: ct
Time: 3 October 2019, 2:20:52.152682 am
UUID: 71c0495c-bf43-b440-aa1b-1cf195eb6a54
Ancestors: HelpSystem-Core-mt.116

Refines accepting text in HelpBrowser

- Revise use of #clearUserEdits and isUpdating
- Use the right #accept: return pattern (Boolean or False)
- Catch an edge case when you try to write something into a nested ClassBasedHelpTopic
- Mark saved methods with a #generated pragma; ask user before overwriting non-auto-generated methods to avoid discarding manual code (such as in SqueakToolsDebuggerHelp>>#usingTheDebugger)

Depends on Tools-ct.894.
