Mucking around with whitespace is necessary with the current version of the 
maxima() function : something here doesn't like to receive empty lines. 
Furthermore, Maxima grammar, a bit Lisp-like (minus parentheses), doesn't 
differentiate betw een quantities of whitespace (in other words, it isn't 
Python :-). So it was simpler to condensate all this whitespace.Of course, 
the present version will have problems for example with strings containing 
semicolons...

Confirmed:-(. Ditto for %r. But in this case, %%R works better (not 
perfectly : it only returns the *last* printed output only (but all graphs. 
Go figure...).

Neither do I:-(.

Meaning we need either a Maxima lexer/parser before calling maxima() or a 
better way yo treat Maxima answers to incorrect or incomplete response. 
Non-trivial in both cases.

I plan to muck around the command-line version to see how it behaves in 
this respect (but when ?). Maybe also the code fpr the (cell-)magic %r and 
%maxima of the Sage notebook, which do The Right Thin (TM)  (if I can make 
head or tail of the code...).
