* text.C (backspacePos0): rewrite to make it simple and allow
deleting empty paragraphs even when keepempty is true. Do not rely on dEPM, since this was silly (bugs 2587 and 2882) (Delete): simplify also and avoid calling backspace. (backspace): small tweak. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/branches/BRANCH_1_4_X@15547 a592a061-630c-0410-9148-cb99ea01b6c8
