Some minor mysteries:
1. I think I know why this happens, but should it be happening?
(%i1) trigsimp(sin(x)^2+cos(x)^2);
(%o1) 1
(%i2) kill(all);
(%o0) done
(%i1) trigsimp(sin(x)^2+cos(x)^2);
2 2
(%o1) sin (x) + cos (x)
2. This is cosmetic only, but can be annoying, e.g., when creating demos:
When a "string" (yes, I know MAXIMA doesn't really have strings, hence the
quotes) containing a linefeed is barfed back, it becomes double spaced. Is
this intentional?
(%i2) "This is a ...
... two line string.";
(%o2) This is a ...
... two line string.
