What's the point?  In text form, it is quite often and, to my taste, quite
normal to use 2 spaces after the full-dot (at the end of the sentence), just
like an extra line between paragraphs.  This way, it is easier to separate
sentences between each other.

In real typography, 1.5-sized space is usually used in such places.  But since
plaintext format has no 1.5-sized space, 2 spaces is used.

I'd send an opposite patch, which adds additional space where it is missing.. :)

Thanks,

Well, out of my first reaction on the inconsistency. I just get a feeling on
this controversy by looking at the length of this Wikipedia page's reference
section:

http://en.wikipedia.org/wiki/Sentence_spacing#References

Does NOT matter for me, anyway :)

Thanks,
Fam
