Nicolas Cellier uploaded a new version of System to project The Trunk:
http://source.squeak.org/trunk/System-nice.1139.mcz

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

Name: System-nice.1139
Author: nice
Time: 3 March 2020, 11:49:13.969231 pm
UUID: f83a4bb3-c9ca-4c3a-b4d1-c4e5adcefd0d
Ancestors: System-mt.1138, System-nice.1128, System-ct.1133

Merge System-mt.1138, System-nice.1128, System-ct.1133

System-nice.1128:
	Nuke windows CE OS support.
Let Win32 VM default to UTF32InputInterpreter rather than MacRomanInputInterpreter.

Note: I think that this method is unused and is just adding confusion to already convoluted code... But it is difficult to analyze the source, so it's better to differ this after 5.3 release if unsure. Unless we have a good set of tests?

System-ct.1133:
	Fix execution-around pattern to forward return value in some during methods

So that
	Utilities useAuthorName: 'Squeak' during: [Utilities authorName]
yields
	'Squeak'
but not
	Utilities.
