* doc/text.n: TIP #104 implementation which generalizes the
* generic/tkText.c: undo/redo stack to not be tied solely to the
* 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).
* unix/Makefile.in: [Patch #554763] (callewart)
* unix/tkUnixDefault.h:
* win/Makefile.in:
* win/makefile.vc:
* win/tkWinDefault.h:
