I disagree. Now, you cannot to show a detail of function in well
readable form. Personally I prefer \sf+ form. Because I can see line
numbers, but \sf form is important for some copy paste operations. I
don't think, so \ef can replace \sf. It is based on my personal
experience. When I have to do some fast fix or fast decision I need to
see a source code of some functions (but I am in customer's
environment). Starting a external editor is slow and usually you can
not there to start your preferable editor.

If I return back then my first idea was to modify current \df command
to some practical form. Later in discussion was decided so new command
will be better.

there is some strange - it didn't find it in my environment. But I
recheck it tomorrow morning.
