André Pönitz 5c2f0c5c46 In insets:
2003-10-14  Andr� P�nitz  <poenitz@gmx.net>

  * insetcollapsable.[Ch]:
  * insettabular.[Ch]:
  * insettext.[Ch]:
  * inset.h: getText() as alternative to getParagraphs()

In src:

2003-10-14  Andr� P�nitz  <poenitz@gmx.net>

	* iterators.[Ch]: new direct access to innermost LyXText and Inset

	* undo.[Ch]: restoring part of 'undo in insets'

	* Makefile.am:
	* undo_funcs.[Ch]: merge with undo.[Ch]

	* tabular.C: small cleansing stuff
