I take care of this in this new function by deleting spaces after
indenting the line around the point of initial breakage. I expect it has
now the same behaviour as before except for the minor bug. Please test.
I completed the doc string with a note one the automatic trailing space
deleting. Shouldn't that be stated or is it too obvious ?
(defun reindent-then-newline-and-indent ()
"Reindent current line, insert newline deleting trailing spaces or tabs,
then indent the new line.
Indentation of both lines is done according to the current major mode,
which means calling the current value of `indent-line-function'.
In programming language modes, this is the same as TAB.
In some text modes, where TAB inserts a tab, this indents to the
column specified by the function `current-left-margin'."
