Formatting, tabs vs spaces.

[Paolo Carlini]

Well, if we want to nitpick, is some cases in the library we are using formatting rules not completely standard to the emacs eyes: for example, I find myself pressing the spacebar by hand to indent the struct / class keyword in templates...

One last observation: in principle empty lines should be, well, empty, but sometimes when I use the automatic emacs formatting facilities, a tab to the same indentation of the previous and next lines spuriously sneaks in and I have to remove it by hand
