I did some housekeeping on some classes in Squeak Chronology that had
line feed characters embedded in method source and class comments. Along
the way I updated the underscore assignments to := and made some trivial
cosmetic fixes. I retained the original author initials and method
timestamps throughout, because all changes involve either the adding
or removing of non-printable control characters, or the removal of
an unnecessary $. at the end of a method (this was to trick Montecello
into accepting the changes).

If you are updating your image through the update stream, these fixes
are effective as of Kernel-dtl.176.mcz in source.squeak.org/trunk.

This is intended to resolve Mantis 5229: "Linefeeds in 22 Methods in
3.9g-7061" and Mantis 5675: "Many method sources and class comments
have been contaminated with Character lf".
