David T. Lewis uploaded a new version of Collections to project The Trunk:
http://source.squeak.org/trunk/Collections-dtl.802.mcz

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

Name: Collections-dtl.802
Author: dtl
Time: 19 July 2018, 12:40:11.186143 am
UUID: 95497d30-f52f-4f82-ac8c-3e65cfa30df1
Ancestors: Collections-cmm.801

Change Text class>>string:runs: to call setString:setRunsChecking: instead of setString:setRuns: to prevent creating a Text with run length not matching string length. This fixes the problem originally reported by Tim Johnson in http://lists.squeakfoundation.org/pipermail/squeak-dev/2018-July/199461.html

Add patch by K K Subbu to fix instantiating text when the string and the runarray are of mismatched lengths. This allows a filein to retain text attributes even if the runarray does not match the string length, as may be the case for a fileIn that had been edited externally (otherwise the text will be converted to a string without the intended attributes).

Ancestors: Collections-dtl.802

Attempt to retain as much styling as possible while filing in text from streams where the runs may fall short or extend beyond the string.

Based on Bob's suggestions at http://lists.squeakfoundation.org/pipermail/squeak-dev/2018-July/199530.html
