Split nsEditor::DeleteSelectionAndCreateNode into two parts,
so that routines like InsertImage which need to set attributes
on the new node before inserting into the tree can do so.
This is somewhat temporary, since the current method isn't undo-able;
undo will be implemented after M4.
added aFirst out param to GetTextProperty, so the caller can know if the first character has the property in the case of aAny=true and aAll=false.
fixed a bunch of places where result was being used incorrectly as a return val from do_QueryInterface
some minor undo/redo fixes to split and join of interior nodes.
trivial to add more properties
finished first cut at SetTextProperty. This triggers lots of crashes in
range/selection code where we're holding onto a stale frame pointer (at
least, that's my best guess.)
synched with Charlie's change-o-rama
added an assert in DeleteTextTxn::Init() checking aNumCharsToDelete vs.
0
NS_ASSERTION(0!=aNumCharsToDelete, "bad arg, numCharsToDelete");
if the number of chars to delete is 0, we shouldn't be creating a
transaction at all. I had never seen this condition arise before
Charlie's checkin, I don't know if he introduced it or if it was a
latent bug I just never tripped over before.
