Support NonStandardIndexNames in doMaintenance

[thomasramm]

There is a bug in doMaintenance

What is the current behavior?
If i start the sript i get some errors like "Incorrect syntax near '-'."
so i changed
Line 364+623: set @sqlcommand = 'alter index ' + @indexName + ' on ' + @currentTableName + ' Reorganize';
To: set @sqlcommand = 'alter index [' + @indexName + '] on ' + @currentTableName + ' Reorganize';

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via http://sqlfiddle.com/
The IndexName is e.g. "ClusteredColumnStoreIndex-20190410-152738"

Which versions of SQL Server and which OS are affected by this issue? Did this work in previous versions of our procedures?
SQL Server 2016 SP2 CU10
