Reindent (1/2).

Browse source 
After trying to tweak gindent so that it does not mess-up my ASCII art, give
and read the help of Vim to setup 'cinoptions' according to my needs
(cino=t0(0).  This changeset reindent some bits that where not indented as they
should.  A future commit will reindent the switch/case according to my (bad)
taste now that I have setup cindent correctly on my system (cino=t0(0:0).
