When a character is deleted via the keyboard by Backspace or Delete key,
an artificial selection is created in SwWrtShell::DelLeft()/DelRight().
Ideally this should not delete flys that may be anchored to the
paragraphs, but unfortunately this may happen if there are only 2 empty
paragraphs in the section, because then the artificial selection cannot
be distinguished by the SwDoc implementation from a selection from
Ctrl+A (Select All), which *should* delete the flys.
So introduce a new flag that needs to be passed down multiple layers so
that SwUndoDelete can use it to determine if flys should be deleted, and
translating it to a flag that had been introduced to preserve flys in
ReplaceRange() previously.
There are a couple more callers that look like they want to "replace"
some text, so guess a bit at where to set this new flag.
(note: of course fly anchored *as char* must be deleted via keys.)
