Summary: Fix for Bug #1229377 - copy/paste memory usage

Initial Comment:
This patch adds a cap to the size of a HistoryModel, so that when copying huge \
amounts of text, the clipboard history model does not use up all available heap \
space. It also limits the size of the previews in the PasteFromListDialog, because \
adding 5 megabytes of text to a JTextArea is a _bad_ idea. This should fix bug \
#1229377 - jEdit's oldest open severe bug (from 2005)!.

Hi, I don't see the problem.
It is trying to show a too long String in the TextArea of the dialog ?

Anyway I had this exception
