Hi Colin, Hi All,

    if in 4.5 one tries to evaluate a doit somewhere in a verdant
transcript, one containing much content, then too much logging will occur
to the changes file.  Instead of the selected doit being logged, the entire
contents of the transcript up to the end of the doit will be logged, and
that can cause parse errors when recovering changes.

So how best to solve this?  Here are some ideas and I wanted to ask
people's opinion

- have CompilationCue remember the position of the source stream and
instead of using "source contents" in streamToLog use "source position;
upToEnd"

- have Parser/Scanner remember the characters parsed in a buffer and take
them from there

- change ReadWriteStream to remember its initial position so that when one
says
    (ReadWriteStream on: (String withAll: ((0 to: 255) collect: [:n| n
asCharacter]))
        from: $A asInteger + 1 to: $Z asInteger + 1) contents
one gets 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
instead of
 '





!"#$%&''()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ'

IMO the last option is the right thing to do but it feels like a big change.

best,
Eliot
