* generic/tkText.h: text widget. The APIs are still private.
* generic/tkUndo.c: This also adds a stack limiting ability and
* generic/tkUndo.h: a -maxundo option to the text widget (in
* library/text.tcl: addition to the options from TIP #26) should
* mac/tkMacDefault.h: users want to limit the undo/redo stack
* tests/text.test: (should not be necessary in most cases).
