[O] underscore behaviour

[Andrea Crotti]

I use names with "_" very often, and I like to export to PDF, because 
it' the one that looks nicest.

But the _ in latex means something different, and I find my output a bit 
messed up.
Isn't it possible to add an automatic quote for every "_" when exporting 
to latex/pdf maybe?

Or is there a better way to write things like function names "__init__" 
or similar?
