Electric-indent inhibit empty line clean.

[Ergus]

Hi:

Is it there any way to avoid that electric-indent-mode clears the indented 
empty lines after RET on them? Because I don't find anything in the 
documentation.
In electric-indent-mode; when starting a new line (1) it is indented properly 
according to the scope, syntax etc, but If I press RET again, then the newer 
(2) line is indented properly too BUT the spaces in the prevoius line (1) are 
deleted if it was empty.
This is actually a very good default behaviour, but in some cases it can 
introduce problems or incompatibilities with other editors who keeps the spaces 
to represent scopes (ej. kdevelop or some python editors). 
Have we an option like electric-indent-inhibit-[something] for this?
Thanks in advance,Ergus
