The following Wikipedia article is the most complete and exhaustive source
I could find while researching the double spacing rules:

http://en.wikipedia.org/wiki/French_spacing

To put it briefly, there are three main conventions about inter-sentence
spacing:

o English spacing a.k.a. American typewriter spacing: two spaces after full stop;

o French spacing, i.e. one space;

o traditional typography, which uses proportional fonts and is therefore not
very much interesting here.

Offhand, it seems that the double spacing convention is being currently used
in a more or less consistent manner throughout Linux docs. It also seems to
me that this can be made a requirement and documented somewhere.

Thanks,
Dmitri
