[news.eclipse.platform] TextEditor problem.

[Dollyn <Dollyn.sun@xxxxxxxxx>]

In the SourceViewerConfiguration class, There is 2 method,
getDefaultPrefix and getIndentPrefixes. The questions are:
1. about the getDefaultPrefix. The document says that "Returns the
default prefixes to be used by the line-prefix operation", so, what is
the line-prefix operation?
2. about the getIndentPrefixes. The document says that "Returns the
prefixes to be used by the line-shift operation", and what is the
line-shift operation.(Is it the auto indent??).

Any example is welecome.

Thanks.
