Very few kerneldoc markups need changes due to ReST introduction, and
usually is just whitespace/blank lines adjustment. Ok, someone could
try to improve the script to make it smarter[1], but, on my experiences
addressing it, usually doing the required changes make it visually
better on both C file and on PDF/LaTeX/HTML outputs.

[1] probably rewriting the entire script to work more like a lexical
interpreter than a bunch of rejex expressions.

IMHO, the best thing with kerneldoc is that it helps to keep the
documentation updated, as it warns when someone change the function
arguments without updating the comments.
