Refactoring = improving the design of existing code without
changing (adding/removing/breaking) functionality.
In the message you quote that uses the term "refactor",
the term is used somewhat incorrectly in my opinion.
Refactoring is NOT AT ALL the process of fixing broken
code which is simply "debugging", not "refactoring".
Refactoring is used to improve the design, the internal
structure of code with the goal of producing "well factored"
code. Well factored code conveys intent very clearly, is as
simple as possible and makes adding new functionality very
easy and natural.
A simple refactoring is "Extract Method", where a new method is
created using a piece of code from withing another method
(or multiple methods) and replacing this piece of code
with a call to the newly created method.
For an in depth definition and comprehensive how-tos
see Martin Fowler's book "Refactoring" (Addison Wesley).
