Independent of any philosophical discussion not allowing a setence to
end with a single ':' is completely idiotic.  Please fix the tooling
instead to allow it, as it is very important for being able to just
write understandable comments.

Patches are welcome, although I don't see any easy way to solve it.

In English, the common case is that a line with ends with a colon is
followed by a list. E. g.

	foo:
	  - bar1;
	  - bar2.

However, in this specific case, it is followed by an ascii artwork. 
The double colon is a notation that tells Sphinx to not parse the
lines at the next block, placing the contents of it inside a literal
block. It is used also when the next lines contain a code example,
in order to avoid parsing things like @, () and * inside the code 
block.

The kernel-doc tool might eventually have some parsing logic that
would replace something to a '::' before sending it to Sphinx.
It could, for example, have a "hint" regex that would expect a
certain sequence of characters to be at the last line, like:

	s/ascii\s+artwork.*:/ascii artwork.*::/
or
	s/code\s+block.*:/code block.*::/

Then, change the kernel-doc comment to use it, like:

 * with an extra smp_mb() like shown at the following ascii artwork:

but IMHO, this is a lot worse than "::": it would be more intrusive
and more error-prune.

Thanks,
Mauro
