You can put a space before and/or after the dot. But the standard way
to do it is no space unless you are putting the method on the next
line. It's entirely a matter or taste, but sticking to styles of coding
that other ppl use will make your code more read able to those people.

You can explain that it is just like in English. You don't put a space
before the dot at the end of a sentence, but you put one after.
You can say that this is the same rule for the Ruby language, but that
it does allow you not put one after.

The first is acceptable ruby: I recall seeing lines split
after a '.'
on Ruby-Talk (possibly from the late Guy Decoux).
I point this out because it is an interesting failure mode
which
may tell us something useful.
I can verify this for Ruby 1.8.7's IRB
13:32:36$ irb

But I don't have a 1.9.1 on any machines yet, so can't
tell you if
that has changed.
