[V3dot10] Some notes on 7130

[Andreas Raab]

Hi -

This is really the first time since I've looked at 3.10 so apologies if 
these issues are known already or come relatively late but I couldn't 
help but notice some oddities while I was looking at the problems that 
Ralph had. Going over the history of what went into 7130 (which is 
great, btw, *much* better than anything before it) I found the following 
issues:

* 7086OpenWorkSpaceFix.cs
I would appreciate it if such changes could go directly into the proper 
repositories (in this case http://squeaksource.com/ToolBuilder). Not 
only does it make maintenance easier it also ensures that the code in 
the image is in sync with the code in the repositories (which in this 
case it isn't).

* 7092TTCFontDNUfix.cs
This "fix" is fundamentally incorrect and shows a lack of understanding 
of how m17n works. It seems that the original causes were here described 
in the bug reports at http://bugs.squeak.org/view.php?id=5451 as well as 
http://bugs.squeak.org/view.php?id=5309 but the problem isn't a 
confusion about "TextStyle defaultFont" vs. "TextStyle default" it's 
that the implicit assumption inside #isFontAvailable is that the default 
font is a StrikeFontSet (which does have a fontArray containing 
encodings). I've reopened http://bugs.squeak.org/view.php?id=5309 for 
this reason.

* 7109ChangesOrganizer-pk.cs
This actually duplicates work that I did for 3.9 and the ToolSet 
abstraction. If you look at the class side of ChangeSet you'll find that 
the entire protocol that is in ChangesOrganizer has been present in 
ChangeSet for, oh about a year or so. It seems that the absence of any 
defined process for integrating changes hit once again (the modification 
of ChangeSorter was part of the original changes that I put forward for 
being able to separate out ToolSets).

* 7110ChangeSorterNotes-wiz.cs
This broke the ability to move changes between two change sets in a dual 
change sorter. To wit: In a dual change sorter, select any single method 
and choose to "move method to other side". Boom.

So much for a quick scan of the changes. BTW, I really appreciate being 
able to look at what was done - without the history I wouldn't have 
found any of the above issues.

Cheers,
   - Andreas
