Here is the current solution, which has been working fine so far
today. (I explained in a separate post how 'autoindent' does not
behave the same as this 'indentexpr'.)
au BufWinEnter * if &ft == "" || &ft == "text"
\ | setlocal indentexpr=indent(prevnonblank(v:lnum-1))
\ | setlocal indentkeys-=o
\ | let b:undo_indent = "setlocal indentexpr< indentkeys<"
\ | endif
au FileType * setlocal indentexpr< indentkeys<
Thanks for your help.
